Metabolite Identification
Common NameEthylthiourea
DescriptionEthylthiourea belongs to the class of organic compounds known as thioureas. These are organic compounds containing the thiourea functional group, a derivative of urea with the general structure (R1(N)R2C(=S)(R3)R4, R1-R4=H, alkyl, aryl), obtained by replacing the carbonyl group of urea with a thiocarbonyl group. Based on a literature review a significant number of articles have been published on Ethylthiourea. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ethylthiourea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ethylthiourea 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.
