Chirality centers of ephedrine

WebMar 19, 2024 · 1 Answer. Al E. Mar 19, 2024. Consider ephedrine, The chirality centers are those at which the α carbon has four different substituents. Hence, the red highlights … 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).
