Chapter 5.SE, Problem 64AP
The naturally occurring form of the amino acid cysteine (Problem 5-63) has the S configuration at its chirality center. On treatment with a mild oxidizing agent, two cysteines join to give cystine, a disulfide. Assuming that the chirality center is not affected by the reaction, is cystine optically active? Explain.
