α-Amylase is used to hydrolyze α bonds of α-linked polysaccharides, such as starch and glycogen. Product is from Bacillus amyloliquefaciens and is supplied as a liquid. α-Amylase has been used in various plant studies, such as metabolism studies in Arabidopsis. α-Amylase from Bacillus amyloliquefaciens has been used to hydrolyze sweetpotato amylopectin to identify cluster structure. The enzyme has been used to hydrolyze sago palm starch to reducing sugars, which are then used for ethanol fermentation by Saccharomyces cerevisiae. The enzyme catalyzes amylolysis of gelatinised waxy maize starch to produce reducing sugars.
