Metabolite Identification
Common Namealpha-Methylene-gamma-butyrolactone
Descriptionalpha-Methylene-gamma-butyrolactone, also known as α-methylidene-γ-butyrolactone or tulipalin a, belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Based on a literature review very few articles have been published on alpha-Methylene-gamma-butyrolactone. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alpha-methylene-gamma-butyrolactone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically alpha-Methylene-gamma-butyrolactone 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.
