Protein Degradation
Categories: Digestion of Macro Nutrients#Cellular Mechanisms Kit
Proteins are made up of chains of amino acids connected through bonds. peptides. In the small intestine, the proteins come into contact with the pancreatic secretion, which is rich in proteolytic enzymes. Such enzymes cleave (break) the bonds peptides until dipeptides, tripeptides and a few amino acids remain resulting from the complete digestion of proteins. Finally, peptidases enzymes present in the microvilli of enterocytes hydrolyze (break down) the dipeptides and tripeptides remaining into amino acids so that they can then be absorbed.
