Metabolite Identification
Common Name(R)-2-Amino-3-(2-propynylthio)propanoic Acid
Description(R)-2-Amino-3-(2-propynylthio)propanoic Acid belongs to the class of organic compounds known as cysteine and derivatives. Cysteine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Based on a literature review very few articles have been published on (R)-2-Amino-3-(2-propynylthio)propanoic Acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). (r)-2-amino-3-(2-propynylthio)propanoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (R)-2-Amino-3-(2-propynylthio)propanoic 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.
