Metabolite Identification
Common NameEthylurea
DescriptionEthylurea belongs to the class of organic compounds known as ureas. Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group. Based on a literature review a significant number of articles have been published on Ethylurea. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ethylurea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ethylurea 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.
