Common NameEthanethioic acid, S-(2-(((2R)-2-(acetylamino)-3-mercapto-1-oxopropyl)amino)ethyl)ester
DescriptionEthanethioic acid, S-(2-(((2R)-2-(acetylamino)-3-mercapto-1-oxopropyl)amino)ethyl)ester belongs to the class of organic compounds known as n-acyl-alpha amino acids and derivatives. N-acyl-alpha amino acids and derivatives are compounds containing an alpha amino acid (or a derivative thereof) which bears an acyl group at its terminal nitrogen atom. Based on a literature review very few articles have been published on Ethanethioic acid, S-(2-(((2R)-2-(acetylamino)-3-mercapto-1-oxopropyl)amino)ethyl)ester. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ethanethioic acid, s-(2-(((2r)-2-(acetylamino)-3-mercapto-1-oxopropyl)amino)ethyl)ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ethanethioic acid, S-(2-(((2R)-2-(acetylamino)-3-mercapto-1-oxopropyl)amino)ethyl)ester 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.
