Alpha-amylase 1B

Definition:

Calcium-binding enzyme that initiates starch digestion in the oral cavity. Catalyzes the hydrolysis of internal (1->4)-alpha-D-glucosidic bonds, yielding a mixture of maltose, isomaltose, small amounts of glucose as well as small linear and branched oligosaccharides called dextrins.
