In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property.

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). Web(S)- (R)- Chiral inversion (unidirectional; [(R)- to (S)-] Drug toxicity.
