In the stabilization of tertiary protein structure, two cysteine residues undergo an oxidation reaction. Which specific functional groups interact to form this bridge?
Q1. In the stabilization of tertiary protein structure, two cysteine residues undergo an oxidation reaction. Which specific functional groups interact to form this bridge?
Answer: Sulfhydryl groups
Explanation: Disulfide bridges form specifically between the sulfhydryl (-SH) groups of cysteine. Hydroxyl groups form hydrogen bonds, not covalent disulfide bridges.
