Process for producing fine self-aggregates

摘要

A novel saccharide chain is built on a surface by bonding a second saccharide to the glycolipid present on the surface of a self-aggregate under mild enzyme chemical reaction conditions. 1) A fine self-aggregate comprising an O-glycoside type glycolipid having the structure represented by the formula (chemical formula 2) below (in the formula X₁ represents a glycosyl group or an oligosaccharide group having two to twenty-nine monosaccharides and R is as defined above), 2) a monosaccharide or its derivative and 3) a glycotransferase or glycolytic enzyme are reacted in water.
