Insulin is a peptide hormone produced by beta cells in the pancreas. It regulates the metabolism of carbohydrates and fats; in addition, it stores fat to be used for energy later. When you eat, your blood sugar increases, which causes insulin to be released.
(please read) Insulin has two peptide chains (the A chain has 21 amino acids and the B chain has 30 amino acids) held together by two disulfide linkages Pepsin: cleaves at the C-terminal side of Phe, Tyr, Leu; butnot at Val or Ala Pepsin cleavageTrypsin cleavageH 3 O + cleavage.
