5-hydroxytryptophan
5-Hydroxytryptophan
5-Hydroxytryptophan (pronounced: five-hy-drox-ee-trip-toe-fan), often abbreviated as 5-HTP, is a naturally occurring amino acid and chemical precursor in the biosynthesis of the neurotransmitters serotonin and melatonin.
Etymology
The term "5-Hydroxytryptophan" is derived from its chemical structure, which consists of a tryptophan molecule that has been hydroxylated at the 5th position.
Function
5-HTP is produced in the body from the amino acid tryptophan as part of the biosynthesis of serotonin. It is then converted into serotonin, a neurotransmitter that plays a key role in regulating mood, appetite, and sleep.
Use in Medicine
In medicine, 5-HTP is used as a dietary supplement for various conditions, including depression, anxiety, and sleep disorders. It is also used for conditions where serotonin is believed to play an important role, including obesity, PMS, migraines, and fibromyalgia.
