Metabolite Identification
Common Name4-[3-(Tetradeca-2,5,8-trien-1-yl)oxiran-2-yl]butanoic acid
Description4-[3-(Tetradeca-2,5,8-trien-1-yl)oxiran-2-yl]butanoic acid, also known as 5(6)-oxido-8,11,14-eicosatrienoic acid or 5,6-EET, belongs to the class of organic compounds known as epoxy fatty acids. These are fatty acids containing an oxirane ring as part of the aliphatic chain. Based on a literature review very few articles have been published on 4-[3-(Tetradeca-2,5,8-trien-1-yl)oxiran-2-yl]butanoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-[3-(tetradeca-2,5,8-trien-1-yl)oxiran-2-yl]butanoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-[3-(Tetradeca-2,5,8-trien-1-yl)oxiran-2-yl]butanoic acid 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.
