Metabolite Identification
Common Name2,4,6,8,10,12-Docosahexaenoic acid, ethyl ester
Description2,4,6,8,10,12-Docosahexaenoic acid, ethyl ester, also known as DH-ethyl ester, belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. Based on a literature review very few articles have been published on 2,4,6,8,10,12-Docosahexaenoic acid, ethyl ester. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,4,6,8,10,12-docosahexaenoic acid, ethyl ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,4,6,8,10,12-Docosahexaenoic acid, ethyl ester 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.
