[edit] D and L in Amino Acid

[edit] Definition

Except for glycine, an amino acid contains a chiral carbon, distinguished by D or L (R or S). In the Fischer projection, which places the carboxyl group upward and amino acid-specific side-chain downward, the amino group must comes either left or right, protruding from the paper plane. If the hydrogen is left and amino group is right, the amino acid is called D, after D-glyceraldehide. If the amino group is left, it is called L.

[edit] DL and RS do not coincide

In the Cahn-Ingold-Prelog (or RS) notation, 19 L-amino acids become S-form (when H is placed behind the paper plane, the amino group, carboxyl group and side chain are arranged anticlockwise). Only L-cysteine becomes R-form because S in its side chain makes the arrangement in the different order: amino group, side chain, and carboxyl group. For this reason, although its tetrahedal configuration is the same as the rest of amino acids, it is R-form. Likewise, cystine is R-form too.

[edit] Glycine has no chiral carbon

Glycine has two Hydrogen branches and therefore not chiral. The amino group of proline is included in the ring sturucture and therefore secondary amine.
