Natural Product Identification
Common Name5-Hydroxytryptophol
Description5-Hydroxytryptophol is a relatively minor metabolite of serotonin that is excreted primarily as the glucuronide conjugate in human urine. 5-Hydroxytryptophol becomes more important quantitatively during alcohol intoxication, when a shift in the metabolism of serotonin occurs from 5-hydroxyindole acetic acid toward increased (15-fold higher) formation of 5-hydroxytryptophol due to the inhibition of aldehyde dehydrogenase by ethanol-derived acetaldehyde. Urinary excretion of 5-hydroxytryptophol has also been shown to be markedly increased for several hours following intake of foods rich in serotonin, such as bananas. Wide interspecies variation has been reported in the metabolism serotonin to 5-hydroxytryptophol; 5-Hydroxytryptophol makes up 35% of the excreted serotonin metabolites in the rat on average and 10 to 20% in several other species. Human UDP-glucuronosyltransferase 1A6 (UGT1A6) plays a predominant role in the glucuronidation of 5-hydroxytryptophol by human liver microsomes. (PMID 15258112 ).
