Metabolite Identification
Common NameDihydroethidium
DescriptionDihydroethidium belongs to the class of organic compounds known as phenylquinolines. These are heterocyclic compounds containing a quinoline moiety substituted with a phenyl group. Based on a literature review a significant number of articles have been published on Dihydroethidium. This compound has been identified in human blood as reported by (PMID: 31557052 ). Dihydroethidium is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Dihydroethidium 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.
