Metabolite Identification

Common Name

3-Amino-2,2-dimethylpropanoic acid

Description

3-Amino-2,2-dimethylpropanoic acid, also known as meaib or 2-methylaminoisobutyric acid, belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. Based on a literature review very few articles have been published on 3-Amino-2,2-dimethylpropanoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-amino-2,2-dimethylpropanoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Amino-2,2-dimethylpropanoic acid 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.
