Metabolite Identification
Common NameLumichrome
DescriptionLumichrome belongs to the class of organic compounds known as flavins. Flavins are compounds containing a flavin (7,8-dimethyl-benzo[g]pteridine-2,4-dione) moiety, with a structure characterized by an isoalloaxzine tricyclic ring. Lumichrome is an extremely weak basic (essentially neutral) compound (based on its pKa). A compound showing blue fluorescence, formed by a photolysis of riboflavin in acid or neutral solution. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lumichrome is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lumichrome 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.
