Metabolite Identification
Common Name1-O-Myristoyl-2-acetyl-glycerol
Description1-O-Myristoyl-2-acetyl-glycerol, also known as 1-MAG or glycerol 1-myristate 2-acetate, belongs to the class of organic compounds known as 1,2-diacylglycerols. These are diacylglycerols containing a glycerol acylated at positions 1 and 2. Based on a literature review very few articles have been published on 1-O-Myristoyl-2-acetyl-glycerol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-o-myristoyl-2-acetyl-glycerol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-O-Myristoyl-2-acetyl-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.
