Abstract
.alpha.-Amylase activity can be determined rapidly and precisely by using as a substrate a modified oligo-saccharide wherein a benzylozymethyl group or a halo-methyl group is bonded to the C.sub.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.
