Product Overview
Alpha-amylase is a functional enzyme that targets and hydrolyzes alpha-glycosidic bonds in large alpha-linked polysaccharides such as starch and glycogen. With a small molecular structure and exceptional stability, it delivers strong resistance to various harsh conditions. It catalyzes the breakdown of starch and glycogen into maltose and glucose to maintain energy supply for humans and animals, and is widely distributed in diverse natural biological systems.
