The peptide hormone insulin is composed of two peptide held together primarily by what mechanism?
A)disulfide bonds between cysteine residues
B)charge-charge interactions between acidic and basic amino acids
C)extensive hydrogen bonding due to the relatively high serine and glutamine content
D)hydrophobic interactions
E)an amide bond formed from the R-groups of a glutamic acid residue and a lysine residue

Question

Quizplus · Accepted Answer

Insulin is composed of two peptide chains, an A chain and a B chain, held together by three disulfide bonds between cysteine residues. These disulfide bonds provide stability and structural integrity to the insulin molecule.
