Step-by-step solution

Insulin from an animal source, though caused some patients to develop allergy or other types of reactions to the foreign protein. Insulin consists of two short polypeptide chains: chain A and chain B, that are linked together by disulphide bridges. In mammals, including humans, insulin is synthesized as pro-hormone which contains an extra stretch called the C peptide. The C peptide is not present in the mature insulin and is removed during maturation into insulin.
