Metabolite Identification
Common NameIsovalerylurea
DescriptionIsovalerylurea, also known as 3-m-bu, 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 a small amount of articles have been published on Isovalerylurea. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isovalerylurea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isovalerylurea 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.
