Metabolite Identification
Common Name5-Hydroxybenzofuran-2(3H)-one
Description5-Hydroxybenzofuran-2(3H)-one, also known as 5-hydroxy-2(3H)-benzofuranone or homogentisic acid gamma-lactone, belongs to the class of organic compounds known as benzofurans. These are organic compounds containing a benzene ring fused to a furan. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. 5-Hydroxybenzofuran-2(3H)-one is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on 5-Hydroxybenzofuran-2(3H)-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5-hydroxybenzofuran-2(3h)-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5-Hydroxybenzofuran-2(3H)-one 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.
