Trypsin Health Dictionary

The chief protein ENZYME of the pancreatic secretion. Secreted by the PANCREAS as trypsinogen (an inactive form), it is converted in the duodenum by another enzyme, enteropeptidase. It changes proteins into peptones and forms the main constituent of pancreatic extracts used for digestion of food. (See PEPTONISED FOODS.)

n. an enzyme that continues the digestion of proteins by breaking down peptones into smaller peptide chains (see peptidase). It is secreted by the pancreas in an inactive form, trypsinogen, which is converted in the duodenum to trypsin by the action of the enzyme enteropeptidase.
