Trypsin:

• Function: Trypsin is an endopeptidase, meaning it cleaves peptide bonds within proteins.

• Substrate: It specifically targets peptide bonds on the carboxyl side of lysine and arginine amino acids.

• Activation: Trypsinogen, the inactive form of trypsin, is secreted by the pancreas and activated in the small intestine by enterokinase.

• Role in Digestion: Trypsin works alongside other enzymes (such as chymotrypsin and carboxypeptidase) to break down dietary proteins into smaller peptides and amino acids, which can be absorbed by the body.
