WebHow many chiral centers are in atorvastatin? Atorvastatin is sold as a single (R,R) diastereoisomer with two chiral centers. With this in mind, how many chiral centers … WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers).
