WebChiral molecules are optically active, meaning they rotate polarized light. The non-superimposable mirror images of a chiral molecule are called enantiomers. The interesting thing about enantiomers is that they rotate polarized light in the exact opposite way of each other, so if one enantiomer rotates it +25, the other will rotate it -25.

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).
