NOVEL COMPOSITIONS FOR NEUTRALIZING TOXIC EFFECTS OF HYDROGEN PEROXIDE IN LIVING CELLS OR TISSUES FIELD OF THE INVENTION The present invention relates to the field of food industry as well as to medicine, more particularly to novel compositions comprising hydrogen peroxide (H ₂ O ₂ ) in combination with glycolic acid, glyoxylic acid, glycine, serine or salts thereofthat allow using H ₂ O ₂ as antimicrobial, especially antibacteraial and antiviral or signaling agent yet neutralizing the toxic effects of the latter on the cell and tissues.The present invention also relates to a food product, an alcoholic/ non-alcoholic beverage, or a nutritional supplement comprising the inventive composition and a method for production thereof. BACKGROUND OF THE INVENTION Notwithstanding the clearly shown progress in the way of achieving enhanced antioxidative actions of a variety of substances that can readily be used in food production to improve the health conditions of living beings, there still remains the need in a specific and effective method for defence against cellular toxicity of hydrogen peroxidethat in the same time would allow usage of H ₂ O ₂ as an antimicrobial or hormetic/signaling agent in all applications mentioned above. Normal oxidative respiration of a cell in a living organism, especially mitochondrial respiration, entails generation of reactive oxygen species (ROS). The latter are generated also by redox enzymes, such as uncoupled nitric oxide synthase, cytochrome P-450 isoforms, and NADPH oxidase subtypes (NOXs), in the form of superoxide. When such short-lived ROS combine with nitric oxide (NO), the highly reactive peroxynitrite (a reactive nitrogen species [RNS]) are formed. Most importantly, superoxide can spontaneously or enzymatically be dismutated to form hydrogen peroxide and molecular oxygen. Hydrogen peroxide has a longer half-life than superoxide, and unlike superoxide, hydrogen peroxide can transfer across lipid membranes by either diffusion or transport through channels, such as aquaporins. For this reason, hydrogen peroxide, can cause oxidative damage to membrane lipids and even DNA and proteins if left unchecked by antioxidant systems. When reacting with Fe2 + (Fenton reaction - Fe ⁺² +H ₂ O ₂ -- Fe ⁺³ +HO-+HO), hydrogen peroxide leads to the formation of the highly reactive and damaging hydroxyl radical. Luckily, the Fenton reaction is limited within a cell, in part, by the lack of free transition metals, but may play a role in oxidative damage under an oxidative stress involving accumulation of high levels of intracellular hydrogen peroxide and liberation of Fe ⁺² from intracellular storage sites. While the above described is true for excess levels of hydrogen peroxide, low levels of the same, however, plays a role as a second messenger in signal transduction by modulating the oxidationstate of redox-sensitive cysteines (Cys) to promote kinase function. Therefore, regulation of hydrogen peroxide is important to avoid formation of highly reactive and damaging radicals on the one hand, and to maintain its low level on the other hand. Cells possess several antioxidant barriers, including enzymatic and non-enzymatic ones. It is known that enzymatic catabolism/inactivation of hydrogen peroxide could be executed by several classes of enzymes, like catalase, glutathione peroxidases (GPxs), peroxiredoxins and some others. Except catalase, almost all of these enzymes require the most abundant cellular ROS scavenger, glutathione, as cofactor. The latter exists in active, reduced (GSH, γ-glutamylcysteinylglycine) and inactive, oxidized states (GSSG). GSH is an obligate co-substrate in the reduction of hydrogen peroxide to water. For instance, GPx-1, one of the most abundant members of the GPx family of enzymes utilizes GSH as a cofactor to reduce hydrogen peroxide, resulting in the formation of oxidized glutathione (GSSG). While glutathione protects against oxidative stress, the same substance, in excess, may also have deleterious effects due to a lack of essential cellular oxidants, which, it has been known for some time, can diminish cell growth responsesand promote apoptotic pathways. Newer evidence points to additional cellular and physiological effects caused by lack of cellular oxidants, such as diminished mitochondrial function, and decreased cellular metabolism. Generally speaking, antioxidants have the ability to donate electrons, which is the power being essential in neutralizing radicals andother reactive species. Accordingly, it seems quite logical that an antioxidant, once oxidized, loses its antioxidant power. This is true for glutathione notwithstanding its constant production. Even more problematic is that most people suffer from glutathione deficiency as a result of aging, stress, medication, and high toxicity levels in the blood. To enjoy the antioxidative benefits, it means that antioxidants should be permanently kept in reduced form or be supplemented with boosting pills, capsules, drips, injections, and even inhalants (e.g. glutathione). However, homeostasis of ROS is one of the mandatory requirements for maintaining the viability of the cellular system. Consequently, upon increasing antioxidant doses to permit the repair of pathological mitochondria, or under careless use of antioxidant doses, mitochondrial ROS may be disturbed and normal mitochondria may also be affected negatively as their levels of ROS may fall below their physiologically acceptable limit. Besides GSH, several other antioxidants are applied. For instance, disclosed in US application US 2014/0335205 are materials and methods for the prevention and treatment of disease conditions associated with oxidative stress or a compromised reducing environment. The reducing agent, such as for example 5-aminosalicylic acid (5-ASA) and/or sodium thiosulfate and/or dihydro lipoic acid and/or alpha lipoic acid (ALA) and/or pyruvate can be an agent capable of reacting with H ₂ O ₂ . This agent can function intracellularly or it can be an extracellularly active agent or both. The extracellular activity, however, will also abolish antiseptic abilities of H ₂ O ₂ . Another strategy in dealing with pathologies originating from mitochondrial dysfunction caused by mitochondrial ROS, is mitochondrial targeting of antioxidants. Some potent therapeutics have arisen from the group of mitochondria-targeted antioxidants, which specifically quench ROS in the organelle. However, despite very encouraging results in the use of mitochondria-targeted antioxidants, the mechanistic principle of delivering these agents is, to some extent, counterproductive. The main problem that arises is that injured mitochondria may carry a lower membrane potential when compared with normal ones and as a result, injured mitochondria are capable of taking up less therapeutic antioxidants than healthy mitochondria. Consequently, understanding the overall benefit of targeting dysfunctional mitochondria in pathological tissue requires furthering the development of alternative techniques to target mitochondria. In an endeavor to regulate hydrogen peroxide and ensure its acceptable level within a cell, it is important to bear in mind that hydrogen peroxide still remains the effective antimicrobial agent and for this reason retaining its acceptable extracellular level is the matter of great importance. Hydrogen peroxide is used for sterilization of water and many raw materials for the food production (e.g. dairy products) and also as antibacterial agent for vegetable/fruit skin treatment (e.g. JPS2228224, JP2007053930). Although being a GRAS (Generally regarded as safe) substance, amounts used for the applications mentioned above are strictly regulated. For instance, pursuant to the Code of Federal Regulations (CHAPTER I--FOOD AND DRUG ADMINISTRATION DEPARTMENT OF HEALTH AND HUMAN SERVICES SUBCHAPTER B--FOOD FOR HUMAN CONSUMPTION), hydrogen peroxide as an antimicrobial agent is used to treat food only within the following specific limitations: milk, intended for use during the cheesemaking process as permitted in the appropriate standards of identity for cheese and related cheese products, whey, starch etc. Diluted solution of H ₂ O ₂ is widely used in medical care as an antimicrobial agent for treatment of oral/nasal or outer ear cavities. It is also applied for disinfection of wounds. Thus, there remains a need in the art for treatment and therapeutic modalities to provide biological instructions to one’s cells that ensure reduction of glutathione, the main antioxidant found throughout the cytoplasm and mitochondria, alongside with its oxidation so as to avoid loss of its antioxidant power and, at the same time, to allow hydrogen peroxide to maintain its required concentration level in the extracellular space as an antimicrobial agent within a body. It is object of the present invention to provide a composition comprising hydrogen peroxide (H ₂ O ₂ ) in combination with glycolic acid, glyoxylic acid, glycine, serine or salts thereofthat allow using H ₂ O ₂ as antimicrobial, antiviral or signaling agent yet neutralizing the toxic effects of the latter on the cell and tissues. Especially, the composition is useful for prophylaxis or treatment of bacterial and viral diseases. Another object of the present invention is to provide a food product, an alcoholic/ non-alcoholic beverage, or a nutritional supplement comprising the inventive composition. The objective of the present invention is solved by the teaching of the independent claims. Further advantageous features, aspects and details of the invention are evident from the dependent claims, the description, the figures, and the examples of the present application. SUMMARY OF THE INVENTION The present invention provides anovel composition that can be used to protect a cell, tissues, organs or a multi-cellular organism, such as animals and humans, against hydrogen peroxide induced oxidative stressbut leaves antimicrobial and hormetic/signaling activities of H ₂ O ₂ intact. The present invention is based on ability of glycolic acid (GA) or its salt glycolate, to fully suppress the deleterious effects of peroxide on mitochondrial activity and growth of cells. This compound acts in the cell by entering serine-glycine metabolism where it is transformed sequentially into glyoxylic acid, glycine and serine. Inventors showed that the antioxidant capacity caused by glycolate depends on two interlocked metabolic pathways: serine-glycine and one-carbon metabolism. In this way, conversion of glycolate into glycine and serine ameliorates the drastically decreased NADPH/NADP ⁺ and GSH/GSSG ratios induced by H ₂ O ₂ treatment. Glyoxylic acid, glycine and serine have similar effects on mitochondrial activity and growth as glycolic acid. Remarkably, the above-mentioned effect of the glycolate is detected only in the presence of H ₂ O ₂ . It appears that H ₂ O ₂ induces enzymes required for metabolism of glycolate and increased biosynthesis of NADPH. Thus, glycolate and its derivative on one hand and H ₂ O ₂ on another, comprise a two-component system that neutralizes toxicity of H ₂ O ₂ in the cell. Thus, in one aspect, the present invention provides anovel composition that can be used to protect a cell, tissue, organ or an organism from H ₂ O ₂ and comprises at least two components, component 1 and component 2, wherein component 1 is selected from the group consisting of glycolic acid, glyoxylic acid, glycine, serine or salts thereof, and component 2 is selected from the group consisting of hydrogen peroxide or substances that are able to generate hydrogen peroxide.

DETAILED DESCRIPTION OF THE INVENTION Oxidative stress causes profound alterations of various biological structures, including cellular membranes, lipids, proteins and nucleic acids, and it is involved in numerous malignancies. Reduced glutathione (GSH) is considered to be one of the most important scavengers of reactive oxygen species (ROS), and its ratio with oxidized glutathione (GSSG) may be used as a marker of oxidative stress. Within cells, total GSH exists free and bound to proteins. Since the enzyme glutathione reductase, which reverts free glutathione from its oxidized form (GSSG) is constitutively active and inducible upon oxidative stress, free glutathione exists almost exclusively in its reduced form. In a resting cell, the molar GSH:GSSG ratio exceeds 100:1, while in various models of oxidative stress, this ratio has been demonstrated to decrease to values of 10:1 and even 1:1. The antioxidant function of GSH is primarily due to its involvement in enzymatic pathways that cells have developed against ROS. The most important pathway involves glutathione peroxidase (GPx) and glutathione reductase (GR). GPx catalyzes the reduction of hydrogen peroxide, which is produced by superoxide dismutase (SOD) through the dismutation of superoxide anions or organic hydroperoxides. GSH and GSH-dependent enzymes act in cooperation to scavenge ROS and/or neutralize their toxic oxidizing effect. These systems act at the same time and in cooperation to protect the human body from ROS. Under oxidative stress conditions, GSH is oxidized to GSSG; thus, the GSH:GSSG ratio is altered. Oxidative stress is manifested by the excessive production of reactive oxygen species (ROS) in the face of insufficient or defective antioxidant defence systems. Oxidative stress causes profound alterations of various biological structures, including cellular membranes, lipids, proteins and nucleic acids. Exposure of cells to hydrogen peroxide, one of the ROS, results in toxicity attributable to DNA damage by reactive oxygen species generated via the Fenton reaction: The hydroxyl radical is an extremely powerful oxidant that reacts with most organic substrates atnearly diffusion-limited rates. While it is true that reduced glutathione is responsible for attuning the antioxidant effects, it was shown that the redox state of nicotinamide adenine dinucleotidephosphate (NADPH) is another factor that modulates oxidative sensitivity. Cells resistant to oxidants are made in the conversion of NADP+ to NADPH. The latter is the major regulator of cellular redox potential and is crucial for the action of different antioxidant systems, including the maintenance of reduced glutathione pools. Thus, regeneration of NADPH from NADP ⁺ is essential for protection against oxidative stress. Upon H ₂ O ₂ challenge, the activity of the major sources of cellular NADPH, is induced by about 2.9-fold. The pyridine nucleotide pools, nicotinamide adenine dinucleotide (NAD) and NADP, are crucial to the intracellular balance between the generation of reactive oxygen species (ROS) and their neutralization. The NAD pool participates in processes driving energy homoeostasis, generally associated with the subsequent production of ROS. The NADP pool, meanwhile, plays a primary role in maintaining the antioxidant defenses, but in some tissues may also serve as a cofactor in free radical generating reactions [1]. Both NAD and NADP act as “electron carriers”, ferrying reducing equivalents between redox reactions taking place inside the cell. In their oxidized forms, NAD ⁺ and NADP ⁺ , both molecules may receive electrons by the addition of a hydride ion, producing the reduced forms, NADH and NADPH. In its reduced form NADPH, represents a universal electron donor, not only to drive biosynthetic pathways. Perhaps even more importantly, NADPH is the unique provider of reducing equivalents to maintain or regenerate the cellular detoxifying and antioxidative defense systems. It is widely accepted that, in humans, the rate of NADPH regeneration is an indicative for protection against oxidative stress. It has been observed by the inventors of the present invention that glycolic acid (GA) can restore the mitochondrial membrane potential in a living organism treated with an oxidant Paraquat (PQ ²⁺ ) that produces superoxide (US 10,434,077 B2). However, GA was unable to restore neither animal growth induced by PQ ²⁺ exposure nor the OCR (Oxygen consumption Rate). The reason of above mentioned observation is that superoxide, can directly inactivate some Fe-S cluster-containing enzymes (e.g. aconitase) and it is also transformed into H ₂ O ₂ . In the present invention it is demonstrated that glycolate can combat massive oxidative stress induced by H ₂ O ₂ and fully neutralize damage induced by it. It is also shown that GA is first converted into glycine and serine, thus entering serine/glycine metabolism. The serine-glycine metabolism is tightly connected with one-carbon metabolism. This way serine and glycine are becoming a source of 5,10-CH ₂ -THF (methylene-tetrahydrofolate), which is required for the regeneration of NADPH from NADP ⁺ . In this way, GA can ameliorate the drastically decreased NADPH/NADP ⁺ and GSH/GSSG ratios induced by H ₂ O ₂ treatment. Metabolization of GA in animals has been reported to occur mainly via its oxidation to glyoxylate, which can subsequently be transaminated to form glycine. In turn, glycine can undergo many transformations, among them, entering one-carbon metabolism (by donating a methyl group to tetrahydrofolate, THF) and the production of cysteine via conversion to serine. Serine/glycine metabolism has been proved to play a central role as a major provider of reducing equivalents to maintain cellular antioxidant systems and the fundamental function of glycolate as a natural antioxidant that improves cell fitness and survival. Effect of glycolic acid, on the other hand, depends on the activity of endogenous antioxidant systems and in particular on GSH. The studies showed also that GA supplementation increases the NADPH/NADP ⁺ ratio, in this way stimulates the regeneration of reduced glutathione, resulting in restoration of the redox potential of the cell acting as a natural antioxidant. Thus, the results of the study clearly demonstrate that GA exerts its action by modulating a major antioxidant defense parameter, namely the ratio of GSH to GSSG (the reduced to the oxidized form of glutathione), one of the most common markers of oxidative stress and the extent of damage caused by it. Moreover, the inventors found that the accumulation of H ₂ O ₂ was diminished in animals co-supplemented with peroxide and GA in comparison to those treated with peroxide alone. Interestingly, it has been revealed that GA supplementation in the absence of H ₂ O ₂ does not have a significant impact. In fact, only the combination of both compounds contributes to the induction of the GA-mediated antioxidant pathway. It has been observed that H ₂ O ₂ addition increases the oxidative stress of the animals while at the same time it is itself an up-regulator of this ROS-scavenging pathway which may work at its maximum efficiency when glycolate is externally supplied. In agreement with the observations of the inventors, it has been extensively reported the peroxide-mediated activation of the transcriptional regulator Nfr-2 and its orthologthattrigger the expression of antioxidant proteins and detoxification enzymes. Thus,H ₂ O ₂ is as an inducer of the transcription factorNrf-2and its ortholog Skn-1that upregulate a plethora of phase II detoxification genes. One of the best known examples of genes induced by this transcription factor is gcs-1encoding Glutamate Cysteine Ligase, the first enzyme in the biosynthesis of glutathione. Thus, the inventors have identified a novel composition that is capable of protecting a cell, tissues, organs or a multi-cellular organism, such as animals and humans, against oxidative stress induced by H ₂ O ₂ . This composition is capable of generating an antioxidative defense by neutralizing ROS, particularly H ₂ O ₂ .

Food Product / Beverage / Nutritional supplement / In another aspect of the present invention, the composition of the present invention is applied to a nutritional supplement, a food product or a beverage. The composition of the present invention can be provided in the form of a drink solution or a capsule. The food product according to the present invention can be dairy product or any other food. The beverage according to the present invention can be a non-alcoholic beverage or an alcoholic beverage. The non-alcoholic beverage according to the present invention is selected from a group consisting ofstill water, fruit juices and vegetable juices, carbonated drinks, and non-alcoholic beer. The food or beverage of the present invention includes juices; soft drinks; alocoholic beverage; teas; lactic acidbacteria beverages; milk product such as fermented milk,butter, cheese, yogurt, processed milk and defatted milk;animal meat products such as ham, sausage and hamburger; fishcake products such as plate-like fish cake, egg products suchas rolled egg with soup or dash~maki in Japanese and egg- tofu;confectioneries such as cookie, jelly, chewing gum, candy,drop and snack; frozen dessert such as ice cream, sherbert andiced lolly; breads; noodles; pickles; smoked food products;dried fishes; fishes boiled in soy sauce or tsukudani inJapanese; salt curing products; soups; condiments; foodmaterials; food additives; or any other forms. The form of thefood and beverage is not particularly limited, and may be inany form, such as solid, powdery, liqud, gel, and slurryforms, so far as it is in a form that is easily ingested. Thefood or beverage includes the feed for nonhuman animals. Further the food or beverage of the present inventionmay be in the forms of powdery foods; sheet-like foods;bottled foods; bottled beverages; retort foods; capsule foods;tablet-like foods; fluid foods; nutritious supplement drinksor the like. Ingesting a high concentration of hydrogen peroxide can lead to confusion, strokes, heart attacks, and clots in the lungs. Hydrogen peroxide, even at small amounts can release hundreds of milliliters of oxygen into the human body. If hydrogen peroxide is ingested, oxygen is formed and can get into the blood vessels and can finally just due to gravity enter the brain, the heart and/or the lungs. Ingesting a low amount of hydrogen peroxide can still lead to mild gastrointestinal effects and to tissue damage. In addtion it was surprisinglyfound that while H ₂ O ₂ addition increases the oxidative stress of animals and humans,the samehydrogen peroxideconcurrently isan up- regulator of the ROS-scavenging pathway which works at its maximum efficiency when glycolic acid, glyoxylic acid, glycine or serine or salts of glycolic acid, glyoxylic acid, glycine or serine is externally supplied. In agreement with the observations of the inventors, H ₂ O ₂ is as an inducer of the transcription factorNrf-2and its ortholog Skn-1that upregulate a plethora of phase II detoxification genes. For instance, it was surprisingly shown that the treatment of mice with an inventive composition of GA and hydrogen peroxide induces about 10% increase of their weight as seen in Example 3 and Figure 9. Thus, the Inventors have surprisingly found and shown that in apart to prevent or drastically decrease the adverse effects of hydrogen peroxide, in orderto benefit from the positive effect of activating or up-regulating the ROS-scavenging pathway, it is actually not sufficient to administer only glycolic acid, glyoxylic acid, glycine, serine or a salt thereof. For these purposes it is actually required to administer glycolic acid, glyoxylic acid, glycine or serine or a salt of glycolic acid, glyoxylic acid, glycine or serine together with hydrogen peroxide, because only this combination of glycolic acid and hydrogen peroxide or glyoxylic acid and hydrogen peroxide or glycine and hydrogen peroxide or serine and hydrogen peroxide or a salt of glycolic acid and hydrogen peroxide or or a salt of glyoxylic acid and hydrogen peroxide or or a salt of glycine and hydrogen peroxide or or a salt of serine and hydrogen peroxide seems to be able to sufficiently activate or to sufficiently up-regulate the ROS-scavenging pathway. Consequently, the compositions of the present invention comprise hydrogen peroxide together with component 1 and component 1 is selected from the group consisting of glycolic acid, glyoxylic acid, glycine, serine or a salt of glycolic acid, glyoxylic acid, glycine or serine. The compositions of the present invention can be provided in form of the pure composition comprising or consisting of glycolic acid, glyoxylic acid, glycine, serine or a salt thereof as component 1 and hydrogen peroxide as component 2. Furthermore, the compositions of the present invention can also be provided as nutritional supplement, a food product or a beverage or a pharmaceutical formulation as disclosed herein.

DESCRIPTION OF FIGURES Figure 1. Glycolate supplementation maintains mitochondrial function and improves animal physiology of peroxide treated C. elegans worms. A) Mitochondrial membrane potential (ΔΨm-MMP) was measured in the different strains after 3 days of treatment via MitoTracker Red CMXROS staining and recording the fluorescence intensities. B) Respiration rates in terms of oxygen consumption rate (OCR) determined after 4 days of treatment using a Seahorse Analyzer and normalized to number of worms. C) Size of worms after 4 days of treatment, where the lengths in µm of at least 20 animals were averaged per condition in each experiment. In D, E and F, life span analysis without FUdR, brood size and embryonic lethality, respectively, is shown for worms that had been exposed to H ₂ O ₂ and 10mM GA, as indicated, during larval development. G) H ₂ O ₂ levels in worms exposed to different conditions for 3 days. Then H ₂ O ₂ accumulation was measured with AmplexRed and fluorescence intensity was normalized to protein levels. 100 mM H ₂ O ₂ , 10 mMglycolate (GA) and 0.5 mM BSO were used as indicated. Error bars represent standard error of the mean (n = 3). Figure 2. Glycolate addition prevents the drop in the antioxidant capacity of glutathione caused by peroxide. A) Total glutathione (GSH + GSSG), B) GSSG and C) Ratio of GSH to GSSG levels in animals exposed to 100mM H ₂ O ₂ and supplemented or not with 10 mMglycolate (GA) and 0.5 mM L-buthioninesulfoximine (BSO). Values were determined after 3 days of treatment and normalized to number of worms. Error bars represent standard error of the mean (n = 3).BSO was used as a substance that opposes the effect of glycolic acid and/or glycine. In the presence of BSO, as evident from Figure 2, the biosynthesis of glutathione was inhibited so that glycolateor glycine cannot neutralize the toxic effect of hydrogen peroxide. Thus, adding BSO to glycolate or glycine will abolish the positive effect of glycolate and glycine and will lead to an increase of the oxidative stress. Figure 3.

B) Worms fed with empty vector (EV) or RNAi bacteria against SHMT (mel-32) genes were incubated with H ₂ O ₂ alone or together with glycolate for 3 days. Error bars represent standard error of the mean (n = 4).100mM H ₂ O ₂ , 10 mMglycolate, 100 μM glycine and 500 μM L-serine. Figure 8. Scheme of the proposed pathway for the glycolate-mediated antioxidant activity. Upon exposure to a strong oxidant (e.g. Paraquat), superoxide (O ₂ ^.- ) is produced that in turn can generate H ₂ O ₂ (see text). Both ROS molecules disturb the mitochondrial activity (oxygen consumption rate and mitochondrial membrane potential, Δ Ψ) and animal growth rate. Exogenously added glycolate (GA) is converted into glycine and serine. This triggers the NADPH/NADP ⁺ ratio that together with the generation of the building blocks for GSH synthesis, glycine and L-cysteine (the latter produced form L-serine), increase the GSH/GSSG ratio. The boosted GSH levels counteract the deleterious effects of H ₂ O ₂ on mitochondrial function and growth but not those of superoxide itself. Figure 9. Influence of a Composition comprising GA and hydrogen peroxide on growth of mice. 4 groups of experimental animals of strain C57Bl_6NCtr, consisting of 11 males in each were established. P - treated with 0,25% hydrogen peroxide in drinking water; G - treated with 0,01M GA in drinking water; PG - treated with a composition of 0,25% hydrogen peroxide and 0,01M GA in drinking water; W - plain drinking water. Experiment were started when animals were 6 weeks old and continued until reaching 16 ^th week of age. Mice were weighted once a week. Figure 10.

As seen more than 99% of bacterial colonies are eliminated within 15 minutes. The composition comprising glycine is as active as the 0.3% solution of hydrogen peroxide alone (white bars). EXAMPLES The present invention is explained in more detail in the following by referring to examples, which are not to be constructed as limitative. In the following description, EXAMPLE 1 Materials and Methods Chemicals Sodium glycolate (G0111, TCI), sodium D-lactate (71716, Sigma), glycine (G7126, Sigma), L-serine (S4500, Sigma), L-glutathione reduced (G4252, Sigma), L- buthioninesulfoximine (B2525, Sigma), hydrogen peroxide (H1009, Sigma), paraquat (sc-257968, SantaCruz biotechnologies or 36541 Fluka® from Sigma–Aldrich), IPTG (15529019, ThermoFisher) were used. [1- ¹⁴ C]-glycolate, [1- ¹⁴ C]-glycine and L-[1- ¹⁴ C]-serine were purchased from HARTMANN ANALYTIC (Braunschweig, Germany). Worm strains and culture conditions C. elegans wild-type (N2) strain was received from Caenorhabditis Genetics Center, USA. Mutant strains were generated using the following primers. ldh-1: AATCAACAATTTTCATGTCT and TAAAAATCGCGCGCATTTGA; C31C9.2 (ghpr-1): TCTCGTATAAACAGAAAATATGG and GGGGCGCTCATTCTGGAAATTGGand F41E6.5 (gox-1): GAAGTTGCGTATGTCCTTCTandATAATTGTTTCGAATCATGG. The injection protocol consisted of a master mix of 15 µl (5 µM of each of the primers, Cas9-Protein NLS [12,5 µM], tracrRNA-IDT [12,5 µM], dpy10 Oligo-IDT [733nM], dpy-10-sgRNA- IDT [2,5 µM] and Protein Buffer- stock [2-3x]) that was injected into young adults of N2 strain. Progeny of the rescued strains were genotyped for homozygous deletion with PCR primers for three generations. All mutants were outcrossed at least twice with the wild type to eliminate background mutations. Double and triple mutants were obtained by crossing single or double mutants and selecting the homozygous progeny by PCR. Worms were maintained at 20°C on nematode growth medium (NGM) agar plates seeded with Escherichia coli NA221 ¹ . Gravid adults on NGM agar plates were treated with alkaline hypochlorite solution (i.e., bleached) to purify eggs. On the day prior to setting up the experiment, eggs obtained after bleaching were allowed to hatch overnight in M9 buffer to obtain synchronized L1 population. For RNAi experiments in liquid, E. coli HT115 containing L4440 empty vector or the indicated cDNA fragment in L4440 was inoculatedin 100 ml of LB containing 100 μg/ml ampicillin and incubated overnight at 37°C in a shaking incubator at 250 rpm. To induce the production of dsRNA, a final concentration 0.8 mM IPTG was added to the collected bacterial pellet diluted 100-fold and incubated overnight at 25°C in a shaking incubator at 250 rpm. Bacteria were then pelleted by centrifugation at 4000 rpm for 5 mins and resuspended in 200 μl S-medium containing 100 μg/ml ampicillin and 0.8 mM IPTG. Peroxide treatment A population of synchronized L1 larvae was added to 30-mlglass tubes containing 2.5 ml of S-complete medium (liquid culture) ² and NA22 or induced RNAibacteria at an OD ₆₀₀ of 1.9.100 mM H ₂ O ₂ , 8 mM GA, 100 mM L-glycine, 500 mM L-serine and 1 mM BSO were added as indicated. Worms were incubated at 15°C and 150 rpm in a shaking incubator for 2-6 days, refreshing the medium every 2 days. Mitochondrial staining and microscopy Mitochondrial staining was performed as described previously ^{3, 4} .Briefly, L1 worms were grown on plate or in liquid culture for 2-3 days at 15°C. Subsequently, they were pelleted in a 15-ml tube, rinsed twice with H ₂ O and resuspended in 100 µl of M9. 5 µM MitoTracker Red CMXRos (Thermo Fisher Scientific, Germany) in DMSO was added to the worm suspension and incubated in this solution for 1.5 hr at room temperature in the dark. Next, the excess dye was washed off with M9 buffer and worms were incubated in 100 µl M9 for 30 min to eliminate the excess dye in the gut. Finally, worms were paralyzed with 0.5 mMLevamizol (Sigma–Aldrich), placed on slides covered with a thin layer of 2% agarose on top of which the coverslip (22×22 mm, Menzel–Glaser no. 1) was fixed using nail polish. We used a Zeiss LSM 700 inverted laser scanning confocal microscope and a Zeiss LCI Plan-Neofluar 63×/1.3 ImmCorr DIC M27 objective to image mitochondria (Zeiss, Germany). MitoTracker Red CMXRos was excited at 555 nm and the emission above 560 nm was acquired by the second PMT. Optical sections at 0.1×0.1×0.5 µm ³ x-y-z resolution were collected in a 4D hyperstack. Final images were adjusted for intensity and merged in Fiji. No non-linear adjustments were made. H ₂ O ₂ measurements. Hydrogen peroxide was measured using the Amplex Red hydrogen peroxide/peroxidase assay kit (Molecular Probes, Eugene, OR), adapting the protocol to C. elegans. In the presence of hydrogen peroxide, Amplex Red is oxidized by horseradish peroxidase to form a red-fluorescent oxidation product whose fluorescence intensity can be measured. To measure ROS production from C. elegans, 5000-7000 L1 worms were exposed to each condition for 2-3 days as indicated and then washed four times in 1 ml of the reaction buffer supplied with the kit. Volumes were adjusted to 700-1200 nematodes/50 μl and 50 μl was pipetted into a 96-well plate. A total of 50 μl of the Amplex Red reaction buffer was then added to the wells, and after 1 hr fluorescence was measured with a fluorescence microplate reader using excitation at 530 ± 12.5 nm and fluorescence detection at 590 ± 17.5 nm. Background fluorescence, determined for a no-H ₂ O ₂ control reaction, was subtracted from each value. The significance of differences between conditions was determined by an unpaired ttest. GraphPadPrism 8.0 was used for these calculations. Three biological replicates were carried out for each condition. Growth rate experiments Synchronized L1 worms were incubated at 15°C on plates or in liquid culture and exposed to different conditions as indicated. Single worms were selected randomly from the plates or aliquots were taken from the liquid cultures and added to NGM plates for immediate visualization. 25 worms per treatment were measured at 24-48 hr intervals and all growth curves were done four times. Images were analyzed using FIJI (Image J) software, with length measurements derived by the sum-total of a number of segmented lines of known length, down the center of the worm as described previously ⁵ . Lifespan, progeny number and embryonic lethality determination Lifespan experiments were performed at 20°C without fluorouracil, as described elsewhere (Liu, 2019). Briefly, for the treatment during larval development worms were incubated in liquid culture under different conditions from L1 until L4, and then transferred onto control NGM plates until death. During the reproductive period ( ~ days 1–8), worms were transferred to fresh plates every other day to separate them from their progeny. Survival was scored every other day throughout the lifespan and a worm was considered as dead when they did not respond to three taps. Worms that were missing, displaying internal egg hatching, losing vulva integrity, and burrowing into NGM agar were censored. Progeny number and embryonic lethality was determined the day after transferring the adult animals to fresh plates. Statistical analyses of lifespan were calculated by Log-rank (Mantel-Cox) tests on the Kaplan- Meier curves in GraphPad Prism. For progeny number and embryonic lethality, the significance of differences between conditions was determined using an unpaired t- test in GraphPadPrism 8.0. All experiments were performed in triplicate. Oxygen consumption assay Oxygen consumption of worms was measured with a Seahorse XF ^e 96 system (Seahorse Bioscience, North Billerica, MA), as previously described ⁴ . L3 larvae of the different strains were grown on plates or in liquid culture and supplemented for 2-4 days as described for each experiment. After removing bacteria and debris, approximately 100 worms were pipetted into each well of a 96-well Seahorse XF ^e assay plate and OCR was measured until it stabilized. Then,3 subsequent measurements were made at 6.5-min intervals. Finally, the exact number of worms in each well was counted and used for normalization. A small number of abnormal readings were also filtered out at this stage. On average, 7–8 wells (technical replicates) were used for each condition. Normalized OCR values were averaged for the last 3 measurements for each strain and condition. Four biological replicates were analyzed for each condition. Quantification of glutathione Sample preparation was performed as described previously with some modifications ⁶ . From each condition ∼10,000 synchronized animals were harvested and washed 3 times with sterile water. Worms were resuspended in PBS buffer and 5-µl aliquots were taken to estimate the total number of worms, after which they were vortexed and frozen immediately with liquid nitrogen. To thoroughly lyse the worms, 5 cycles of freezing and thawing were performed in a water bath at 37°C, followed by a 1-min sonication. The samples were then centrifuged and the supernatant tested for protein estimation and GSH quantification. Total GSH, GSSG, and GSH/GSSG ratios were quantified using the GSH/GSSG-Glo assay kit (Promega) following the instructions of the manufacturer. Briefly, each sample was tested in triplicate in 96-well culture plates with total glutathione or GSSG lysis reagent, for total glutathione or GSSG measurement, respectively. The GSH probe, luciferin-NT, was converted to luciferin, which is coupled to a firefly luciferase. The plates were then read in an EnVisionLuminometer plate reader (Perkin Elmer, United States). The GSSG value was subtracted from the total glutathione to calculate GSH levels and GSH/GSSG ratio. Four biological replicates were analyzed for each condition.

NADPH and NADP ⁺ quantification

To measure NADP ⁺ and NADPH from C. elegans, 10000-15000 L1 worms were exposed to each condition in duplicates for 3 days and then washed four times with H ₂ O. After taking an aliquot for protein estimation, worms were resuspended in 100 pl of H ₂ O and 230 μlot Eluent A (95% acetonitrile, 0.1 mM ammonium acetate and 0.01% NH ₄ OH) was added together with 1 μl of 1 μM chloropropamide as internal standard. 25 □M solutions of each nucleotide were treated in parallel as standards. Homogenization for 15 min at 4°C and 300gwas carried out in a TissueLyser II (Qiagen)after adding 1/3 volume of 0.5 mm zirconium beads. The resulting mixture was centrifuged at 13,000g and the supernatant transferred to a new tube.

LC-MS/MS analysis of the samples was performed on a high-performance liquid chromatography (HPLC) system (1200 Agilent) coupled online to G2-S QTOF (Waters). For normal phase chromatography Bridge Amide 3.5 ml (2.1x100mm) column from Waters was used. The mobile phase composed of eluent A and eluent B (40% acetonitrile, 0.1 mM ammonium acetate and 0.01% NH ₄ OH) was applied with the following gradient program: Eluent B, from 0% to 100% within 18 min; 100% from 18min to 21 min; 0% from 21 min to 26 min. The flow rate was set at 0.3 ml/min. The spray voltage was set at 3.0 kV and the source temperature was set at 120ºC. Nitrogen was used as both cone gas (50 L/h) and desolvation gas (800 Uh), and argon as the collision gas. MS ^E mode was used with Bridge Amide 3.5 □I (2.1x100mm) column in ESI negative ionization polarity for the detection of the nucleosides. Mass chromatograms and mass spectral data were acquired and processed by MassLynx software (Waters). Three and four biological replicates were analyzed for each condition of mel-32 RNAi and EV, respectively. Quantitative real-time PCR. The differential expression of F41E6.5 (gox-1), C31C9.2 (ghpr-1), gcst-1, mel-32 and gcs-1genes was measured using qRT–PCR. ~5000 L1 N2 worms were exposed to each condition for 3 days at 15 °Cas described above and then washed three times with H ₂ O. Total RNA was isolated using the RNeasy Mini Kit (Qiagen)and equal amounts of all samples were reverse transcribed with SuperScript III (Invitrogen) using oligo(dT)12–18 primers. cDNA quality was tested using standard PCR. qRT– PCR was performed using pre-designed TaqMan Gene Expression Assay (ThermoFischer Scientific) with at least three samples in triplicates. For the relative quantification of gene expression levels, the 2 ^-ΔΔCT method and results were normalized to the expression level of the cdc-42 gene. Expression levels were averaged over technical and biological replicates, Radioactive labelling. To quantify the uptake of glycolate, glycine and L-serine approximately 10000 synchronized L1 were incubated in liquid cultures as described above and grown for 3 days in the presence of 10 Ci of [1- ¹⁴ C]-glycolate, [1- ¹⁴ C]-glycine or L-[1- ¹⁴ C]- serine. At this stage, worms were snap-frozen and stored at 80°C.Animals were lysed by freezing/thawing and extracted by using the Bligh and Dyer method ⁷ . After phase separation, organic and aqueous fractions were recovered from the lower and upper phases, respectively. After drying and concentration, radioactivity was quantified using a scintillation counter and normalized for total number of worms. Statistical information The number of biological replicates is stated above for each method. Results shown as means; error bars represent the standard error of the mean. The unpaired Student’s t-test was used to determine statistical significance of differences between means (P < 0.05 [*], P < 0.01 [**], P < 0.005 [***]) unless otherwise stated. EXAMPLE 2: Glycolate neutralizes the toxic effects of H ₂ O ₂ on an organism Glycolate counteracts the deleterious effects of H ₂ O ₂ on mitochondrial function, animal reproductive capacity and lifespan When larvae of the nematode C. elegans were treated with peroxide, there was a drop in MMP, but coincubation with GA prevented this effect (Figure 1A). H ₂ O ₂ also induced a decline in the respiration rate and a concomitant growth delay (Figure 1B and 1C). Remarkably, GA was able to restore both traits (Figure 2B and 2C). BSO treatment prevented the GA-mediated improvement in MMP, OCR and growth rate, thus strongly indicating that glutathione synthesis is fundamental for the observed oxidative stress relief mediated by GA (Figure 1A, 1B and 1C). Notably, GAsupplementation also ameliorated the shortened lifespan and reduced reproductive capacity caused by H ₂ O ₂ . Animals exposed to H ₂ O ₂ during larval stages and transferred to control plates as young adults showed a significantly reduced lifespan (Control worms: 18.5 +/- 1.19 days; H ₂ O ₂ worms: 5.88 +/- 1.47 days [p = 0.0006]). Addition of GA significantly increased lifespan (14.13 +/- 0.51 days [p = 0.015]) making it comparable to that of untreated worms (Figure 1D). A similar positive effect was observed when analyzing brood size and embryonic lethality in animals that had been treated only with H ₂ O ₂ or in combination with GA (Figure 1E and F, respectively). Glycolate supplementation prevents the drop in GSH/GSSG ratio caused by H ₂ O ₂ exposure Glutathione is a tripeptide composed of glycine, cysteine and glutamate that coexists in two interconvertible forms: a reduced one, GSH, and an oxidized glutathione disulfide (GSSG), which is produced upon interaction with oxidative molecules. To test if GSH and GSSG concentrations are affected when treating C. elegans larvae with H ₂ O ₂ and GA, glutathione levels upon exposure to peroxide were quantified (Figure 2). It was observed that H ₂ O ₂ treatment caused a significant decrease in total glutathione compared to non-treated animals, but this parameter was partially restored in the presence of GA (51% [p= 0.0457] and 91% [p=0.1231] of the control, respectively). The effect of GA was again lost, however, if the inhibitor BSO was included in the medium (65% of the control [p=0.0051]) (Figure 2A). More notable was the dramatic increase in the oxidized form of glutathione caused by H ₂ O ₂ , an effect that was also prevented by addition of GA (513% [p=0.0253] and 140% [p=0.0778] of the control, respectively) (Figure 2B). One of the most common markers of oxidative stress and the extent of damage caused by it is the ratio of the reduced to the oxidized form of glutathione (GSH/GSSG) ⁸ . Remarkably, it was obtained a 10-fold reduction in this parameter in worms incubated with peroxide alone but only a 28% decrease if GA was included in the medium (GSH/GSSH per worm = 107.5 in control; 11.3 in H ₂ O ₂ [p=0.0078] and 77.4 in H ₂ O ₂ +GA [p=0.103]). The effect of the latter was partially prevented by inhibition of glutathione synthesis with BSO (GSH/GSSG per worm = 36 [p=0.012]) (Figure 2C), in agreement with previously reported alterations of redox homeostasis caused by this inhibitor. These results clearly demonstrate that GA exerts its action by modulating a major antioxidant defense parameter, namely the ratio of GSH to GSSG. Moreover, the accumulation of H ₂ O ₂ was diminished in animals co- supplemented with peroxide and GA in comparison to those treated with peroxide alone, but unchanged if glutathione synthesis was blocked by BSO (Figure 1G). Oxidation of glycolate is a prerequisite for its activity How treatment with GA can lead to an increase in GSH/GSSG ratio? Therefore, the underlying metabolic pathways that could link alterations in glutathione levels to GA itself or some of its downstream metabolites were explored. Metabolization of GA in animals has been reported to occur mainly via its oxidation to glyoxylate (Figure 3) ^{9- 11} , which can subsequently be transaminated to form glycine. In turn, glycine can undergo many transformations, among them, entering one-carbon metabolism (by donating a methyl group to tetrahydrofolate, THF) and the production of cysteine via conversion to serine (Figure 3, KEGG pathway database). To test whether glycolate needs to be metabolized to exert its antioxidant activity, it was sought to obtain a mutant unable to catalyze the oxidation of glycolate to glyoxylate. In C. elegans, there are three enzymes that can be potentially responsible for this reaction (Figure 3). The corresponding genes are: F41E6.5 (gox-1), encoding the ortholog of the human glycolate oxidase (HAO-1); ldh-1 (encoding the lactate dehydrogenase), which has been found to have glyoxylate reductase activity ^12-13 ; and C31C9.2. The latter is predicted to encode the phosphoglycerate dehydrogenase involved in the biosynthesis of serine, but its sequence displays the highest homology to the human glyoxylate reductase/hydroxypyruvate reductase, reported to catalyze the interconversion of glyoxylate and glycolate ^14-17 (Figure 3). From here, this gene will be designated as ghpr-1 (Glyoxylate/HydroxypyruvateReductase-1). Single mutants of gox-1 and ldl-1, or their double mutants showed no reduction in the effect of glycolate on MMP, OCR or growth. The deletion mutant of ghpr-1, however, displayed a significantly reduced effect of glycolate on MMP, oxygen consumption rate and developmental rate upon H ₂ O ₂ treatment (Figure 4A-4C). Remarkably, the glycolate-mediated protection was totally abolished in the ghpr-1; gox-1; ldh-1 triple mutant strain, demonstrating the overlapping activities of these three enzymes (Figure 4A-4C). To test whether the reduction or absence of positive effects of GA on these mutants is due to deficient ROS-scavenging abilities, relative glutathione levels were quantified. Interestingly, both ghpr-1 and ghpr-1; gox-1; ldh-1 strains exhibited decreased levels of total glutathione compared to untreated N2 worms, a situation that was worsened by peroxide treatment but, in contrast to wild-type animals, unaffected by the addition of GA (Figure 5A). Additionally, the significant increase in the oxidized form of the antioxidant, GSSG, observed in animals treated with peroxide, was not rescued by co-incubating the mutants with GA (Figure 5B). A similar lack of response to GA was observed when analyzing the ratio of GSH to GSSG (Figure 5C). These results clearly demonstrate that oxidation of GA is catalyzed mostly by GHPR-1 but also by GOX-1 and LDL-1 and suggest that further metabolization of this compound is crucial for its protective role on mitochondrial function and growth upon oxidative damage. Relief of oxidative stress requires entry of glycolate into serine-glycine metabolism According to the scheme in Figure 3, glycolate can be converted into glycine and L- serine via the serine-glycine metabolic pathway. Can these amino acids also have a positive influence on C. elegans larvae exposed to peroxide? Indeed, both glycine and L-serine were able to restore MMP, respiration, growth and GSH/GSSG ratio to control levels when added to H ₂ O ₂ -treated worms (Figure 4 and 5). Moreover, both glycine and L-serine supplementation could overcome the deleterious effects of peroxide on strains deficient in the oxidation of glycolate (single ghpr-1 and ghpr-1; gox-1; ldh-1 triple mutants). Thus, these compounds are downstream effectors in the metabolic pathway of GA, as depicted in Figure 3. The next step was to understand the molecular mechanisms underlying the action of these two amino acids. Glycine is a component of the tripeptide glutathione, but it can also be converted into L-serine, which is a precursor of L-cysteine, another building block of GSH. However, more important perhaps is the conversion of glycine to L-serine that feeds one-carbon metabolism with THF as a key player (Figure 3). Transformation of glycine into L-serine requires two enzymatic activities: one catalyzed by serine hydroxymethyltransferase (SHMT, encoded by mel-32) and the other by the glycine cleavage system (GCS, composed of the subunits T, P, L and H) (Figure 3) ^18-20 . Through the action of GCS, glycine can provide a methyl group for the production of 5,10-methylene-H4 folate (5,10-CH ₂ -THF), which together with another unit of glycine is a substrate of SHMT for the synthesis of L-serine (Figure 3). The action of GA, glycine and serine on worms upon knock down of the SHMT and the GCS activities by RNAi against mel-32 or gcst-1 (encoding SHMT and subunit T of the GCS in C. elegans, respectively) was tested (Figure 3). Remarkably, none of these three compounds were able to restore either MMP, OCR or growth rate, in contrast to the restored parameters exhibited in worms fed with empty vector RNAi bacteria (Figure 6A-6C). Moreover, the GSH-to-GSSG ratio that was maintained close to control levels when worms fed with empty vector were grown in the presence of GA, glycine or serine (Figure 6D), was strongly reduced in animals defective in either mel-32 or gcst-1 independently of their supplementation with any of these three metabolites (Figure 6D). In addition, animals defective in glycolate oxidation (ghpr-1 and the ghpr-1, ldh1, gox-1 mutants) exhibited a loss of response to glycine and L-serine when fed with mel-32 RNAi bacteria. With this, it is demonstrated that functional SHMT and GCS activities are essential for the observed GA-, glycine- and serine-mediated protection against oxidative damage. Supporting this conclusion, life-span extension caused by GA supplementation of worms treated with peroxide was lost in mel-32-knockdown animals. Note, GA supplementation in the absence of H ₂ O ₂ does not have a significant impact on any of the parameters analyzed (Figure 1 and 2). This suggests that treatment with H ₂ O ₂ could induce the expression of one or more of the proteins involved in the GA-metabolizing pathway (Figure 3). In fact, it has long been established the role of H ₂ O ₂ as inducer of the transcription factor Nrf-2 and its C. elegansortholog Skn-1 that upregulate a plethora of phase II detoxification genes ^21-25 . One of the best known examples of genes induced by this transcription factor is gcs-1 encoding Glutamate Cysteine Ligase, the first enzyme in the biosynthesis of glutathione ^8,27,28 . Therefore, the relative expression levels of 5 different genes by RT-PCR upon peroxide or glycolate supplementation, including gcs-1 were analyzed. Remarkably, four of the tested genes (gox-1, ghpr-1, mel-32 and gcs-1) exhibited a significant induction when worms were exposed to different peroxide concentrations. The only exception was gcst-1, the expression of which was not significantly altered by the treatments. Unexpectedly, GA also moderately induced expression of these genes. This demonstrates that both compounds contribute to the regulation of the GA-mediated antioxidant pathway. Although, their specific roles could differ. Glycolate supplementation restores the NADPH/NADP ⁺ ratio impaired by peroxide treatment Considering that both SHMT and GCS can produce 5,10-CH ₂ -THF, which is required for the regeneration of NADPH from NADP ⁺ (Figure 3), the most plausible explanation for the increase in GSH/GSSG ratio caused by GA is the alteration of NADPH levels. NADPH is the major regulator of cellular redox potential and is crucial for the action of different antioxidant systems, including the maintenance of reduced glutathione pools ^8,24,27 (Figure 3). A series of recent publications has demonstrated that, in proliferating cells, the pentose phosphate pathway and the previously underestimated THF metabolism have nearly comparable contributions to the regeneration of NADPH from NADP ^{+ 29-32} (Figure 3). Thus, GA and consequently glycine could increase NADPH by entering serine-glycine metabolism. When subjected to H ₂ O ₂ treatment, C. elegans larvae showed a significantly decreased ratio of NADPH to NADP ⁺ (Figure 7). However, when animals were supplemented with either GA or glycine in the presence of H ₂ O ₂ , the proportion of the reduced to the oxidized nucleotides was fully rescued (Figure 7A), in agreement with the restoration of GSH/GSSG under the same conditions (Figure 2C). L-serine supplementation, on the other hand, provoked a much weaker, but still significant, increase in the proportion of NADPH to NADP ⁺ (Figure 7A). This observation cannot be explained by a reduced uptake of L-serine by the worms compared to that of GA or glycine since radioactivity measured in animals labelled with [ ¹⁴ C]L-serine was actually 3 times higher than in those labelled with [ ¹⁴ C]GA. Instead, the modest effect of L-serine on NADPH levels could be due to the fact that in C. elegans, SHMT is prone to synthesize serine from glycine ¹⁸ . Nevertheless, excessive amounts of exogenously added L-serine most probably cause the shift of equilibrium towards glycine and thus generate the improved reducing capacity of the worms. In addition, the conversion of L-serine to L-cysteine (Figure 3) could also have a positive impact on GSH levels without affecting the relative amounts of NADP ⁺ and NADPH. Consistent with the emerging contribution of one-carbon metabolism to the regeneration of NADPH, knocking down of the C. elegans SHMT enzyme, MEL-32, caused a reversal of the NADPH/NADP ⁺ ratio compared with worms fed with empty vector (Figure 7B). Exposure of these mel-32 knocked down worms to H ₂ O ₂ produced a further decline in the proportion of the reduced to the oxidized nucleotides, which was not significantly affected by co-supplementation with GA. This correlates again with the ineffectiveness of GA addition on GSH/GSSG ratio in worms fed with mel-32 RNAi (Figure 6D and 7B). With this one can conclude that glycolate exerts its beneficial effects on C. elegans exposed to oxidative stress via the glycine-serine pathway that feeds one-carbon metabolism and the folate cycle, and in this way, improves the redox state of the animals (Figure 8). EXAMPLE 3: Influence of a Composition comprising GA and hydrogen peroxide on growth of mice The experimental treatment of wild-type mice (strain C57Bl_6NCtr) was performed as follows: 4 groups of experimental animals were established, 11 males in each group. Group A: was treated with 0,25% hydrogen peroxide (H ₂ O ₂ ) in drinking water Group B: was treated with 0,01M GA in drinking water Group C: was treated with a composition of 0,25% hydrogen peroxide (H ₂ O ₂ ) and 0,01M GA in drinking water Group D: was on plain drinking water Experiment were started when animals were 6 weeks old and continued until reaching 16 ^th week of age. Mice were regularly weighted once a week. As can be seen in Figure 9, the treatment of mice with a composition of GA and hydrogen peroxide induces about 10% increase of their weight. Remarkably, H ₂ O ₂ alone has also a slight positive effect. EXAMPLE 4: A method of preparing a food product containing the composition of the present invention Pasteurized milk and mix of bacterial starters for making Joghurt, Matsoni, Dahi, Bathora that comprise Individual bacterial cultures comprising the following bacterial strains: Lactobacillus coryniformis, Lactobacillus delbrueckii, Lactobacillus rhamnosus, Lactococcuslactis, and Streptococcus thermophiles is provided. Next, the established amount known in the art of particular starter or bacterial culture is mixed with the milk and the mixture is fermented under aerobic conditions by contacting the milk with air. After forming the texture of the fermentation product with the thickness of up to substantially 2 cm, the hydrogen peroxide concentration in the surface layer is measured and upon achieving the hydrogen peroxide concentration within the range of 30 ppm to 50 ppm, the surface layer is removed and refrigerated so as to reduce the fermentation process therein. Then the mass remaining after the step of removing the surface layer is further fermented by repeating the preceding steps until the last surface layer has been fermented. Finally, all layers containing the hydrogen peroxide are combined. The component 1 is added before or after the step of fermentation. EXAMPLE 5 A method of preparing a beverage containing the composition of the present invention Pasteurized juice and mix of bacterial starters for making Joghurt, Matsoni, Dahi, Bathora that comprise Individual bacterial cultures comprising the following bacterial strains: Lactobacillus coryniformis, Lactobacillus delbrueckii, Lactobacillus rhamnosus, Lactococcuslactis, and Streptococcus thermophiles is provided. Next, theestablished amount known in the art of particular starter or bacterial culture is mixed with the juice and the mixture is fermented under aerobic conditions by contacting the juice with air; the hydrogen peroxide concentration is measured within the mass of the fermented mixture, and the component 1 is added when the hydrogen peroxide concentration reaches the amount of 30ppm to 50ppm. EXAMPLE 6: Anti-viral effect of drug according to the present invention. The drug composition is tested according to the test of evaluation of the potential activity against a rhinovirus responsible for colds on fully differentiated human airway epithelial cells culture. The compositions are applied together with infectious virus and the incubation is carried out for 5 hours. 2 rinsing steps with the drug formulations are carried out. The remaining is collected and the RNA is dosed after cell lysis. The same collecting step is carried out 24 hours after and the same dosing step is carried out. The percentage expressed the changes in viral RNA, resulting in the 98% of inhibition of rhinovirus replication, leading to the anti-viral efficacy. In addition to the above described test, a kit comprising component 1 and component 2 was applied, wherein the component 2 was administered 15 minutes later than the component 1 was administered. The result in terms of inhibition of rhinovirus replication was the same as with the administration of the above mentioned drug composition. EXAMPLE 7: Antimicrobial effect of a composition comprising hydrogen peroxide and glycine on Staphylococcus aureus bacterial culture, according to the present invention. A composition comprising 0.5% Glycine and 0.3% Hydrogen peroxide was prepared on 0.9% sodium chloride solution. Water was sterile purified. 4.5 ml of the composition was added to the sterile test tubes containing 0.5 ml of Staphylococcus aureus bacterial culture (ATCC 25923, compatible with McFarland standard 2) with titer of around 10 ⁶ . After desired times, hydrogen peroxide was neutralized by 1 ml of sterile 2.5% sodium bisulfite solution. (Previously it was demonstrated that 2.5% sodium bisulfite solution on itself had no antimicrobial effect). After incubation for 4-5 minutes, sample from each test tube was diluted 1000 times with sterile water, and 100 ml was spread evenly on standard tryptic soy agar petri plate. Plates were incubated at 37°C for 24 hours and bacterial colonies were counted. As a positive control (100% survival), was taken a sample, where the composition was neutralized by sodium bisulfite instantly (Figure 10). EXAMPLE 8: Assessing effects of compositions comprising GA, glycine or serine and hydrogene peroxide on viability of cells, according to the present invention. Materials Cells: T3M4 (Fast growing pancreatic cancer cells); Media: Standard medium - DMEM / 10% FBS; Treatment medium - PBS / 10% FBS. Experimental setup Cells were grown under standard condition and were seeded in 96-well plate (5000 cells per well). Treatment was started after 12 hrs. After replacement of Standard medium with Treatment medium, cells were treated with different doses of H ₂ O ₂ . For cell viability assessment 10µl MTT solution (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) were added into each well. In 3-4 hours medium was be aspirated. After the plate was dried, formed formazan was solubilized with isopropanol and reads of absorbance at 570nm and 630nm wavelengths were taken. Measurements at Time Zero (12hrs.), Day-1 (+24hrs.), Day-2 (+48hrs) and Day-3 (+72hrs.) were recorded. All values have been normalized and cell growth curve was build. Each treatment group was measured in quadruples and the experiment was repeated for 3 times. As first, we identified toxic dose of H ₂ O ₂ . After this, we have continued with 2 selected H ₂ O ₂ doses and applied different concentrations of GA, glycine or serine. We also had an additional control group, containing only the latter compounds. Groups at each time points have been statistically compared. Cytotoxicity assessment plate example:
