Common Name18-Hydroxyeicosapentaenoic acid
Description18-hydroxyicosa-2,4,6,8,10-pentaenoic acid belongs to the class of organic compounds known as hydroxyeicosapentaenoic acids. These are eicosanoic acids with an attached hydroxyl group and five CC double bonds. Based on a literature review very few articles have been published on 18-hydroxyicosa-2,4,6,8,10-pentaenoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 18-hydroxyeicosapentaenoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 18-Hydroxyeicosapentaenoic 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.
