| Common
name: |
Tryptophan |
|
| Chemical
name: |
[2-Amino-3-(3-indolyl)propionic acid] |
|
| Isomerism: |
The Tryptophan
molecule has a chiral center at the carbon connected to the
carboxylic acid and the amine groups. Hence, it has 2 optical
isomers: D-tryptophan or [(R)-2-Amino-3-(3-indolyl)propionic acid],
and L-tryptophan [(S)-2-Amino-3-(3-indolyl)propionic acid].
L-tryptophan is the amino acid precursor of serotonin and melatonin.
