Tryptophan
General Chemical Information


HTML version Author: Kimberly Dick   

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.
Empirical formula: C11H12N2O2
