(a) Interpretation: The R , S system configuration for α - carbon of L- cysteine is to be stated. Concept introduction: The naming of the chiral center and geometric isomers are based on Cahn-Ingold-Prelog priority rules. If the priority assigned to each group attached to the chiral center in a molecule is in a clockwise direction, then it is the R-stereoisomer, and if this is counter-clockwise, then it is the S-stereoisomer. R and S-stereoisomer are mirror images of each other. The line-and-wedge representation is used to show the molecule in three dimensions.
