Metabolite Identification
Common Name1,2-Dipalmitoyl-rac-glycero-3-phosphoethanolamine
Description1,2-Dipalmitoyl-rac-glycero-3-phosphoethanolamine, also known as DHPE or dipalmitoyl cephalin, belongs to the class of organic compounds known as phosphatidylethanolamines. These are glycerophosphoetahnolamines in which two fatty acids are bonded to the glycerol moiety through ester linkages. Based on a literature review very few articles have been published on 1,2-Dipalmitoyl-rac-glycero-3-phosphoethanolamine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-dipalmitoyl-rac-glycero-3-phosphoethanolamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Dipalmitoyl-rac-glycero-3-phosphoethanolamine 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.
