Pepsin is the active protein-digesting enzyme of the stomach. Pepsin acts on protein molecules by breaking the peptide bonds that hold the molecules together. Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase. These enzymes also get some help from the brush border enzymes found in the small intestine.
Protein digestion follows a very rigid process; the purpose is to break down the protein into smaller components, called amino acids, which are used to rebuild or replace damaged or dying proteins in the body after digestion is complete.
