| Common Name | (14R,15S)-14,15-Epoxy-5,8,11-icosatrienoic acid |
|---|
| Description | (14R,15S)-14,15-Epoxy-5,8,11-icosatrienoic acid, also known as 14,15-epoxy-5,8,11-eicosatrienoate or 14,15-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 (14R,15S)-14,15-Epoxy-5,8,11-icosatrienoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). (14r,15s)-14,15-epoxy-5,8,11-icosatrienoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (14R,15S)-14,15-Epoxy-5,8,11-icosatrienoic 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. |
