Common Name(S)-2-Amino-4-methylsulfanyl-butane-1-thiol
Description(S)-2-Amino-4-methylsulfanyl-butane-1-thiol belongs to the class of organic compounds known as alkylthiols. These are organic compounds containing the thiol functional group linked to an alkyl chain. Based on a literature review very few articles have been published on (S)-2-Amino-4-methylsulfanyl-butane-1-thiol. This compound has been identified in human blood as reported by (PMID: 31557052 ). (s)-2-amino-4-methylsulfanyl-butane-1-thiol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (S)-2-Amino-4-methylsulfanyl-butane-1-thiol 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.
