Product Introduction
L-5-Hydroxytryptophan powder is a white to pale yellow powder to crystals. 5-Hydroxy-L-tryptophan is a naturally occurring amino acid from the essential amino acid L-tryptophan. 5-Hydroxy-L-tryptophan is a precursor to neurotransmitters, which are chemicals that transmit nerve impulses across the gaps between neurons called synapses. These neurotransmitters include serotonin and melatonin.

Product Application
L-5-Hydroxytryptophan powder is a monoamine neurotransmitter involved in the regulation of mood, cognition, reward, learning, memory, sleep, and many other physiological processes. It has been used to treat diseases such as depression, migraines, and insomnia.
Chemical analysis of 5-HTP is primarily performed using high performance liquid chromatography (HPLC) coupled with different detectors, including diode array (DAD), fluorescence (FD), and mass spectrometry (MS). Separation is typically performed using reverse phase C-18 column chromatography. The binary solvent system is H2O acidified with 0.1% v/v formic acid (solvent A) and acetonitrile acidified with 0.1% v/v formic acid (solvent B). Chromatograms are typically recorded at 230 and 270 nm.
In addition to HPLC, other chromatographic techniques have been used to detect and quantify 5-HPT. Capillary electrophoresis (CE) has been used with different detectors to determine 5-HTP in commercial dietary supplement samples, platelet-rich human plasma, and immortalized rat raphe neurons. A rapid separation of 5-HTP was developed using micellar electrokinetic chromatography with diode array detection. The identification and quantification of 5-HTP were also achieved by solid phase extraction pretreatment combined with gas chromatography-mass spectrometry based on a modified silylation derivatization method.
