Metabolite Identification
Common Name(2-Acetyloxy-3-octadecoxypropyl) 2-(trimethylazaniumyl)ethyl phosphate
Description(2-{[2-(acetyloxy)-3-(octadecyloxy)propyl phosphonato]oxy}ethyl)trimethylazanium belongs to the class of organic compounds known as 1-alkyl,2-acetylglycero-3-phosphocholines. These are glycerophosphocholines that carry exactly one acetyl chain attached to the glycerol moiety through an ester linkage at the O2-position, and one alkyl chain attached through an ether linkage at the O1-position. Based on a literature review very few articles have been published on (2-{[2-(acetyloxy)-3-(octadecyloxy)propyl phosphonato]oxy}ethyl)trimethylazanium. This compound has been identified in human blood as reported by (PMID: 31557052 ). (2-acetyloxy-3-octadecoxypropyl) 2-(trimethylazaniumyl)ethyl phosphate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (2-Acetyloxy-3-octadecoxypropyl) 2-(trimethylazaniumyl)ethyl phosphate 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.
