Most naturally occurring amino acids have chiral centers (the asymmetric a carbon atoms)that are named (S) by the Cahn–Ingold–Prelog convention (Section 5-3). The commonnaturally occurring form of cysteine has a chiral center that is named (R), however.(a) What is the relationship between (R)-cysteine and (S)-alanine? Do they have the oppositethree-dimensional configuration (as the names might suggest) or the same configuration?(b) (S)-Alanine is an l-amino acid (Figure 24-2). Is (R)-cysteine a d-amino acid or anl-amino acid?
