The inactive precursor of trypsin, secreted in the pancreatic juice.
Oxford Dictionary of Sports Science & Medicine:
trypsinogen |
An inactive precursor of trypsin secreted by the pancreas.
Oxford Dictionary of Biochemistry:
trypsinogen |
the pancreatic zymogen precursor of trypsin. It is secreted in pancreatic juice and in the duodenum is cleaved by enteropeptidase, which cleaves the Lys8-|-Ile9 bond in trypsinogen, to yield β trypsin.

It has been suggested that this article or section be merged into trypsin. (Discuss) Proposed since October 2011. |
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.
Serum trypsinogen is measured using a blood test. High levels are seen in acute pancreatitis and cystic fibrosis.
