Metabolite Identification
Common Name1-Palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol
Description1-(acetyloxy)-3-(hexadecanoyloxy)propan-2-yl octadeca-9,12-dienoate belongs to the class of organic compounds known as triacylglycerols. These are glycerides consisting of three fatty acid chains covalently bonded to a glycerol molecule through ester linkages. 1-(acetyloxy)-3-(hexadecanoyloxy)propan-2-yl octadeca-9,12-dienoate is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-Palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol 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.
