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). WebAug 28, 2024 · Chiral Compounds.

A meso compound is one which satisfies both of the following criteria: (1) it must have chiral centers and (2) it must have an internal plane of symmetry. On the other hand, an achiral compound is one which has an internal plane of symmetry. Thus you can say because a meso compound has an internal plane of symmetry, it is in fact achiral and ...
