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 occurs mainly in the stomach and also in the small intestine. When protein food is eaten and enters the stomach, the hydrochloric acid in the stomach denatures the protein. This means it starts to break the protein down into short chains of amino acids joined together (peptide chains).
