PROCESS FOR PREPARING ALPHA-(1,4) LINKED OLIGOSACCHARIDE

摘要

The present invention relates to a process for preparing .alpha.-(1,4) linke d oligosaccharide, and more particularly, to a process for preparing oligosaccharide expressed by Formula (1) by reacting amylose, easily availab le from the natural product, with enzyme under a specific condition. Since the oligosaccharide prepared from the present invention is .alpha.-(1,4) linked and has a suitable sugar distribution, the same is particularly useful as source material for preparing optically pure (S)-3-hydroxy-.gamma.- butyrolactone.
