Alpha-amylase assay using modified oligosaccharide and process for producing said modified oligosaccharide.

摘要

alpha -Amylase activity can be determined rapidly and precisely by using as a substrate a modified oligosaccharide wherein a benzyloxymethyl group or a halo-methyl group is bonded to the C6 position of non-reducing-end glucose residue and the reducing-end glucose residue is bonded to a group which exhibits an optically measurable change upon cleavage. Processes for producing such a compound are also disclosed.
