Trypsinogen
From Wikipedia, the free encyclopedia
Trypsinogen (EC 3.4.23.18/20/21/23/24/26) is the precursor form of the pancreatic enzyme trypsin. It is found in pancreatic juice, along with amylase, lipase, and chymotrypsinogen. It is activated by enterokinase, which is found in the intestinal mucosa, to form trypsin. Once activated, the trypsin can activate more trypsinogen into trypsin.
Serum trypsinogen is measured using a blood test. High levels are seen in acute pancreatitis, and cystic fibrosis.
