Question

Quizplus · Accepted Answer

Disulfide bonds are covalent bonds that form between the sulfur atoms of two cysteine residues, which can be distant from each other in the linear sequence of amino acids. These bonds play a crucial role in stabilizing the tertiary structure of proteins by holding different parts of the protein together. They can also be involved in stabilizing quaternary structures when present, but the question does not mention quaternary structure. Disulfide bonds do not stabilize primary or secondary structures directly.
