Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B 3 (niacin). [4] It is encoded by the codon UGG.
Tryptophan hydroxylase (TPH) is an enzyme (EC 1.14.16.4) involved in the synthesis of the monoamine neurotransmitter serotonin. Tyrosine hydroxylase , phenylalanine hydroxylase , and tryptophan hydroxylase together constitute the family of biopterin-dependent aromatic amino acid hydroxylases .

Serotonin and tryptophan have been found in chocolate with varying cocoa contents. The highest serotonin content (2.93 μg/g) was found in chocolate with 85% cocoa, and the highest tryptophan content (13.27–13.34 μg/g) was found in 70–85% cocoa. The intermediate in the synthesis from tryptophan to serotonin, 5-hydroxytryptophan, was not found.
