Trypsinogen Trypsinogen (EC 3.4.23.18/20/21/23/24/26) is the precursor form or zymogen of the pancreatic enzyme trypsin. It is found in pancreatic juice, along with amylase, lipase, and chymotrypsinogen. It is activated by enteropeptidase, which is found in the intestinal mucosa, to form trypsin. Once activated, the trypsin can activate more trypsinogen into trypsin. Trypsin cleaves the peptide bond on the carboxyl side of basic amino acids such as arginine and lysine. ==Function== Trypsinogen, as a precursor of trypsin, functions as storage of an inactive form of trypsin so that it may be kept in pancreas and released in significant amount when required for protein digestion. it is released by the pancreas itself along with other enzymes.
