Metabolite Identification
Common NameN-(2-Hydroxyethyl)acrylamide
DescriptionN-(2-Hydroxyethyl)acrylamide, also known as PNHEA or polyduramide, belongs to the class of organic compounds known as n-acylethanolamines. N-acylethanolamines are compounds containing an N-acyethanolamine moiety, which is characterized by an acyl group is linked to the nitrogen atom of ethanolamine. Based on a literature review very few articles have been published on N-(2-Hydroxyethyl)acrylamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-(2-hydroxyethyl)acrylamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-(2-Hydroxyethyl)acrylamide 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.
