Insulin is monomeric and is composed of two polypeptide chains. There are two different types of chains. Chain A has 21 amino acids and Chain B has 30 amino acids. Insulin has a three dimensional structure consisting of 3 helices and 3 conserved disulfide bridges.

Insulin has a three dimensional structure consisting of 3 helices and 3 conserved disulfide bridges. The molecules in insulin sometimes form dimers in solution due to the hydrogen bonding between the B chains.
