Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands it comprises a small portion of the total amylase excreted, which is mostly made by the pancreas. Amylase all amylases (glycoside hydrolases) catalyze the breakdown of complex sugars (such as starch) and act at α-1,4-glycosidic bonds the concentration of pancreatic and salivary amylase can be several orders of magnitude greater than that in other tissues/organs such as lungs, tears, sweat, and human milk.
