| 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. |
