Chymotrypsinogen B Overview

Chymotrypsinogen B is an inactive precursor (zymogen) of chymotrypsin B, a digestive serine protease enzyme. It is synthesized in the acinar cells of the pancreas and secreted into the small intestine, where it is activated to its enzymatic form. The active enzyme cleaves peptide bonds on the carboxyl side of aromatic amino acids in dietary proteins.

Mechanism of Action

Inhibition of chymotrypsin activity (after activation)

Biological Functions

Protein digestion
Proteolysis

Disease Associations

Pancreatic disorders

Safety Considerations

  • Autodigestion of pancreatic tissue if prematurely activated
