protein

• endopeptidases = hydrolyse INTERNAL peptide bonds into shorter chains
• exopeptidase = hydrolyses terminal amino acids from the ends of polypeptides (amino or carboxyl)
• dipeptidases = break down remaining dipeptides into amino acids
• endopeptidases are produced by stomach and pancreas
• exopeptidases are produced in the pancreas and secreted in the small intestine
• dipeptidases are produced by the epithelium of the small intestine
• endopeptidases break long chain polypeptides into shorter chain polypeptides. exopeptidases break down short chain polypeptides into dipeptides and amino acids. dipeptidases break down dipeptides into amino acids
