Metabolite Identification
Common NameIsobutyramide
Description2-methylpropanimidic acid belongs to the class of organic compounds known as primary carboxylic acid amides. Primary carboxylic acid amides are compounds comprising primary carboxylic acid amide functional group, with the general structure RC(=O)NH2. Based on a literature review very few articles have been published on 2-methylpropanimidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isobutyramide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isobutyramide 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.
