Metabolite Identification
Common Name(2-Ethylcrotonoyl)urea
Description(2-Ethylcrotonoyl)urea belongs to the class of organic compounds known as n-acyl ureas. N-acyl ureas are compounds containing an urea bearing a N-acyl group. Based on a literature review very few articles have been published on (2-Ethylcrotonoyl)urea. This compound has been identified in human blood as reported by (PMID: 31557052 ). (2-ethylcrotonoyl)urea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (2-Ethylcrotonoyl)urea 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.
