Metabolite Identification

Common Name

2-Pivalamidoacetic acid

Description

2-Pivalamidoacetic acid, also known as N-pivaloylglycine, belongs to the class of organic compounds known as n-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. Based on a literature review a significant number of articles have been published on 2-Pivalamidoacetic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-pivalamidoacetic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Pivalamidoacetic 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.
