Describe the digestion of proteins

In the stomach the endopeptidase breaks the internal peptide bonds of the protein forming smaller polypeptide chains. In the duodenum the smaller polypeptide chains are hydrolysed by exo and endo peptidase to release amino acids and di peptides. therfore in the ileum membrane bound dipetidase hydrolysed the peptide bond of the dipeptide to form amino acids.
