Solution

Insulin:
The A chain and B chain are the two peptide chains that make up insulin.
Two disulfide bonds bind the A and B chains together, and an extra disulfide bond is created inside the A chain.
The A chain and the B chain in the majority of organisms each have 21 and 30 amino acids, respectively.
