A digestive enzyme secreted from the pancreas into the intestine. Chymotrypsin breaks down large protein molecules into there constituent molecules – amino acids.

A digestive enzyme (formed in the small intestine) which breaks down polypeptides or proteins.

An enzyme present in the intestines that breaks down proteins when combined with trypsin (which is secreted by the pancreas). This enzyme is absent or reduced in patients with pancreatitis.

An enzyme secreted by the pancreas into the small intestine to assist in protein breakdown.

Chymotrypsin (bovine γ chymotrypsin: , ) is a digestive enzyme that can perform proteolysis. Chymotrypsin cleaves peptides at the carboxyl side of tyrosine, tryptophan, and phenylalanine, although over time it also hydrolyzes other amide bonds, particularly those with leucine-donated carboxyls.
