IUBMB Comments
Acts on starch, glycogen and related polysaccharides and oligosaccharides in a random manner; reducing groups are liberated in the alpha-configuration. The term "alpha" relates to the initial anomeric configuration of the free sugar group released and not to the configuration of the linkage hydrolysed.
