WebApr 14, 2024 · Chirality is an essential concept in stereochemistry and refers to the property of a molecule that cannot be superimposed on its mirror image. Chiral molecules are non-superimposable mirror images of each other and exist as enantiomers. 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).

WebSep 16, 2016 · Chirality derives from the symmetry and geometric arrangement of the molecule, and often results in optical activity. Optical activity is derivative in nature; chiral compunds tend to be optically active. It is is derived from the interaction of chiral materials with polarized light.
