Vedclass · Answer

(C) Insulin is composed of two peptide chains referred to as the $A$ chain and $B$ chain. The $A$ chain consists of $21$ amino acid residues and the $B$ chain consists of $30$ amino acid residues. These two chains are linked together by two inter-chain disulphide bridges. Additionally,there is one intra-chain disulphide bridge within the $A$ chain. Therefore,the total number of disulphide linkages in insulin is $3$.
