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). http://www.chem.ualberta.ca/~vederas/Chem_164/handouts/pdf/sugars.pdf
