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.
Tryptophan ball and stick model spinning. Tryptophan (symbol Trp or W) [3] is an α-amino acid that is used in the biosynthesis of proteins.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.
Serotonin, an endogenous amine, is a neurotransmitter derived from the amino acid tryptophan. Serotonin is involved in regulating mood, sleep, appetite, and sexuality. [9] The amines are transmitted locally or via the blood system. The exogenous amines are directly absorbed from food in the intestine. Alcohol can increase the absorption rate.
Tryptamine is known to act as a serotonin receptor agonist, although its potency is limited by rapid inactivation by monoamine oxidases. [5] [6] [14] [31] [32] It has specifically been found to act as a full agonist of the serotonin 5-HT 2A receptor (EC 50 Tooltip half-maximal effective concentration = 7.36 ± 0.56 nM; E max = 104 ± 4%).

Eat a healthy diet: Eating foods rich in tryptophan, like eggs, tofu, dairy, turkey and spinach, can positively impact serotonin levels, Freimuth says. Viswanathan adds that some foods, like ...
Examples are dopamine, norepinephrine and serotonin. All monoamines are derived from aromatic amino acids like phenylalanine, tyrosine, and tryptophan by the action of aromatic amino acid decarboxylase enzymes. They are deactivated in the body by the enzymes known as monoamine oxidases which clip off the amine group.
“Tryptophan can become serotonin — the brain chemical that calms, causes sleep, among other things — if the right enzymes are around to do so,” she notes.
A common example of an indolamine is the tryptophan derivative serotonin, a neurotransmitter involved in mood and sleep. [1] Another example of an indolamine is melatonin . In biochemistry , indolamines are substituted indole compounds that contain an amino group.
