L-5-Hydroxytryptophan-d3（Cat No.:S000583） is a specialized form of 5-hydroxytryptophan (5-HTP), a precursor to serotonin and melatonin, neurotransmitters involved in mood regulation and sleep-wake cycles. The “d3” designation indicates that three hydrogen atoms in the 5-HTP molecule are replaced with deuterium, a stable isotope of hydrogen. This isotopic substitution enables precise tracking of 5-HTP metabolism and its conversion into serotonin and melatonin using techniques like mass spectrometry. L-5-Hydroxytryptophan-d3 serves as a valuable tool in neurochemical studies, aiding in the elucidation of serotonin and melatonin pathways, and facilitating research into mood disorders, sleep disorders, and related therapeutic interventions.
