Protein digestion begins in the stomach with the action of an enzyme that we previously learned about called pepsin. Pepsin is the active protein-digesting enzyme of the stomach. When pepsin acts on the protein molecule, it breaks the bonds that hold the protein molecule together, called peptide bonds.
Digestion of Proteins in the Small Intestine. Trypsin and chymotrypsin are pancreatic protease enzymes secreted by the pancreas that are involved in protein and fat digestion. From the stomach, protein digestion carries on in the duodenum, which represents the first segment of the small intestine.
