Metabolite Identification
Common NameMonoelaidin
DescriptionGlyceryl monooleate, also known as monolein or mono-oleoylglycerol, belongs to the class of organic compounds known as 1-monoacylglycerols. These are monoacylglycerols containing a glycerol acylated at the 1-position. Glyceryl monooleate 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 ). Monoelaidin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Monoelaidin 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.
