Metabolite Identification
Common NameMethanesulfinic acid
DescriptionMethanesulfinic acid, also known as methylsulfinate or msa acid, belongs to the class of organic compounds known as sulfinic acids. Sulfinic acids are compounds containing a sulfinic acid functional group, with the general structure RS(=O)OH (R = organyl, not H). Based on a literature review a significant number of articles have been published on Methanesulfinic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Methanesulfinic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Methanesulfinic 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.
