Metabolite Identification
Common Name2-Cyclohexen-1-one
Description2-cyclohexen-1-one, also known as 3-oxocyclohexene, belongs to the class of organic compounds known as cyclohexenones. Cyclohexenones are compounds containing a cylohexenone moiety, which is a six-membered aliphatic ring that carries a ketone and has one endocyclic double bond. 2-cyclohexen-1-one is a green, pesticide, and roasted tasting compound. Based on a literature review a significant number of articles have been published on 2-cyclohexen-1-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-cyclohexen-1-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Cyclohexen-1-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.
