Description6-(hydroxymethyl)-11-methoxy-1,10-dimethyl-5-oxo-4,14-dioxatricyclo[9.2.1.0³,⁷]tetradeca-2,6-dien-8-yl 2-methylbut-2-enoate belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. 6-(hydroxymethyl)-11-methoxy-1,10-dimethyl-5-oxo-4,14-dioxatricyclo[9.2.1.0³,⁷]tetradeca-2,6-dien-8-yl 2-methylbut-2-enoate 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 ). Vernolide a is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Vernolide A 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.
