Common Name(Z)-7-((2S,3R)-3-((2Z,5Z)-Undeca-2,5-dienyl)oxiran-2-yl)hept-5-enoic acid
Description(Z)-7-((2S,3R)-3-((2Z,5Z)-Undeca-2,5-dienyl)oxiran-2-yl)hept-5-enoic acid, also known as 8,9-epoxyeicosatrienoate or 8,9-EET, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Based on a literature review very few articles have been published on (Z)-7-((2S,3R)-3-((2Z,5Z)-Undeca-2,5-dienyl)oxiran-2-yl)hept-5-enoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). (z)-7-((2s,3r)-3-((2z,5z)-undeca-2,5-dienyl)oxiran-2-yl)hept-5-enoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (Z)-7-((2S,3R)-3-((2Z,5Z)-Undeca-2,5-dienyl)oxiran-2-yl)hept-5-enoic 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.
