Vedclass · Answer

(C) Insulin is a peptide hormone produced by the beta cells of the pancreas. It consists of two polypeptide chains: the $A$ chain and the $B$ chain. The $A$ chain contains $21$ amino acids,and the $B$ chain contains $30$ amino acids. These two chains are linked together by disulfide bridges. Therefore,the total number of amino acids in a mature insulin molecule is $21 + 30 = 51$ amino acids.
