Metabolite Identification
Common NameHarmol glucuronide
Description3,4,5-trihydroxy-6-({1-methyl-9H-pyrido[3,4-b]indol-7-yl}oxy)oxane-2-carboxylic acid belongs to the class of organic compounds known as phenolic glycosides. These are organic compounds containing a phenolic structure attached to a glycosyl moiety. Some examples of phenolic structures include lignans, and flavonoids. Among the sugar units found in natural glycosides are D-glucose, L-Fructose, and L rhamnose. 3,4,5-trihydroxy-6-({1-methyl-9H-pyrido[3,4-b]indol-7-yl}oxy)oxane-2-carboxylic acid is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Harmol glucuronide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Harmol glucuronide is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
