Which amino acid can be involved in special covalent "disulfide bridges" that, when present, help to stabilize the tertiary and quaternary structure of proteins?

Question

Quizplus · Accepted Answer

Cysteine is unique among the amino acids in its ability to form disulfide bridges (bonds) due to the presence of a thiol (-SH) group in its side chain. These disulfide bonds play a crucial role in stabilizing the tertiary and quaternary structures of proteins by linking different parts of a protein molecule or different protein molecules together.
