Common Name | 1,2-Distearoylphosphatidylethanolamine |
---|
Description | 1,2-Distearoylphosphatidylethanolamine, also known as DSPE or PE 18:0, 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 a small amount of articles have been published on 1,2-Distearoylphosphatidylethanolamine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-distearoylphosphatidylethanolamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Distearoylphosphatidylethanolamine 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. |
