Oligosaccharide derivatives and their use as substrate for measuring alpha-amylase activity.

摘要

An oligosaccharide derivative having 4 to 7 glucose units wherein a primary alcohol moiety positioned at the 6-position of the non-reducing end glucose unit is replaced by

or the like group and the 1-position of the reducing end glucose unit is replaced by a phenoxy or substituted phenoxy group or an umbelliferyl group or an indoxyl group is particu- lady suitable as a substrate for measuring a-amylase activity.
