Which of the following is an important biological reaction of thiols? A) the combination of two thiols and the elimination of H₂S to yield a thioether B) the reduction of two thiols to form a disulfide C) the oxidation of two thiols to form a disulfide D) none of the above

Question

Quizplus · Accepted Answer

The oxidation of thiols to form disulfides is an important biological reaction that can occur intra- and intermolecularly. Disulfide bonds are important for stabilizing protein structure and for regulating protein activity. Choice A describes a thiol/thiol exchange reaction, which is important for regulating protein activity and signaling pathways. Choice B describes the reduction of a disulfide bond, which is also important for regulating protein activity. However, the question is specifically asking about the important biological reaction of thiols, not disulfides or thioethers.
