(a) Interpretation: In the R , S system the α − carbon configuration of L- cysteine is to be stated. Concept introduction: The absolute configuration of a molecule is a spatial arrangement of atoms. It is represented by two terms R and S where R refers to rectus and S refers to sinister. Whether the molecule is assigned either R or S configuration is based Cahn-Ingold-Prelog rule. It is based on the priority order of the substituents which is based on the atomic number. If the priority order is clockwise then it is assigned R configuration otherwise S configuration. Also, the lowest priority group is kept away from the observer.
