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. Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.

Salivary amylase is the primary enzyme in saliva. Salivary amylase breaks down carbohydrates into smaller molecules, like sugars. Breaking down the large macromolecules into simpler components helps the body to digest starchy foods, like potatoes, rice, or pasta. During this process, larger carbohydrates, called amylopectin and amylose, are broken ...
As a group, kallikreins are enzymes that take high molecular weight (HMW) compounds, like kininogen, and cleave them to smaller units. Salivary kallikrein breaks down kininogen into bradykinin, a vasodilator. Bradykinin helps to control blood pressure in the body. It causes blood vessels to dilate or expand and causes blood pressure to be lowered. ...
Lingual lipase is an enzyme that breaks down triglycerides into glycerides and fatty acid components, thus catalyzing the digestion of lipids. The process begins in the mouth where it breaks down the triglycerides into diglycerides. Unlike salivary amylase, which functions best in non-acidic environments, lingual lipase can operate at lower pH valu...
Saliva contains other minor enzymes, like salivary acid phosphatase, which frees up attached phosphoryl groups from other molecules. Like amylase, it helps with the digestion process. Saliva also contains lysozymes. Lysozymesare enzymes that help to kill bacteria, viruses and other foreign agents in the body. These enzymes thus perform antimicrobia...

Salivary amylase. References. Amylase. An amylase ( / ˈæmɪleɪs /) is an enzyme that catalyses the hydrolysis of starch (Latin amylum) into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion.
