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) the reaction of thiols with hydrochloric acid to form thiolate salts

Question

Quizplus · Accepted Answer

The oxidation of two thiols to form a disulfide bond is an important biological reaction of thiols. This reaction is commonly used in the formation of protein tertiary and quaternary structure, as disulfide bonds help to stabilize the protein's shape. Choice A is incorrect because it describes the formation of a thioether, not a biological reaction. Choice B is incorrect because it describes the reduction of disulfide bonds, not a biological reaction of thiols. Choice D is incorrect because it describes an acid-base reaction, not a biological redox reaction.
