Optimal activity of alpha amylase of M w of 45 ... AMY is produced and stored in salivary glands and the pancreas and secreted into the digestive tract and eventually into the bloodstream. It is rapidly excreted into the urine because of its relatively small mass.
WebSalivary 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. Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into t …
