摘要：
α-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 C 6 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.
