D)protein bonds

Question

Quizplus · Accepted Answer

The bonds that hold the two chains of an insulin molecule together are disulfide bonds. These covalent bonds form between two cysteine amino acids on each chain, creating a bridge that connects the two chains. Peptide bonds connect amino acids within a single chain, while ionic bonds and protein bonds are not involved in the structure of insulin.
