Title:
PROCESS FOR PRODUCING SUGAR CHAIN ASPARAGINE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO2004070046
Kind Code:
A8
Abstract:
A process for producing sugar chain asparagine derivatives from defatted egg yolk, which comprises: (a) a step in which defatted egg yolk is treated with a proteinase to produce a sugar chain peptide mixture; (b) a step in which the sugar chain peptide mixture is treated with a peptidase to produce a sugar chain asparagine mixture; (c) a step in which a lipid-soluble protective group is introduced into sugar chain asparagines in the sugar chain asparagine mixture to produce a sugar chain asparagine derivative mixture; and (d) a step in which the sugar chain asparagine derivative mixture is subjected to chromatography to separate it into sugar chain asparagine derivatives.
