Metabolite Identification
Common NameMethacrylamide
Descriptionmethacrylamide belongs to the class of organic compounds known as primary carboxylic acid amides. Primary carboxylic acid amides are compounds comprising primary carboxylic acid amide functional group, with the general structure RC(=O)NH2. methacrylamide is an extremely weak basic (essentially neutral) compound (based on its pKa). Methacrylamide is an industrial chemical used in the production of polymers and copolymers. This compound has been identified in human blood as reported by (PMID: 31557052 ). Methacrylamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Methacrylamide 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.
