Metabolite Identification
Common NameErythrocentaurin
Description1-oxo-3,4-dihydro-1H-2-benzopyran-5-carbaldehyde belongs to the class of organic compounds known as 2-benzopyrans. These are organic aromatic compounds that 1-benzopyran, a bicyclic compound made up of a benzene ring fused to a pyran, so that the oxygen atom is at the 2-position. 1-oxo-3,4-dihydro-1H-2-benzopyran-5-carbaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Erythrocentaurin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Erythrocentaurin 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.
