Trypsin is an enzyme produced in the pancreas as an inactive precursor called trypsinogen which is then secreted into the small intestine and activated by enterokinase.
Trypsin helps in the digestion process of protein molecules by converting a long chain of amino acids into a small chain.
Trypsin is also referred to as a proteolytic enzyme, or proteinase.
This digestive enzyme also activates other pancreatic enzymes such as chymotrypsinogen, proelastase, procarboxypeptidase, and prolipase.
Trypsin hydrolyses the peptide bonds present in proteins, breaking them into smaller peptides.
Trypsin cleaves peptide bonds at the carboxyl side of lysine or arginine residues.
