Metabolite Identification
Common NameMethanethiol
DescriptionMethanethiol (also known as methyl mercaptan) is a colorless gas that smells like rotten cabbage. It is a natural substance found in the blood, brain, and other tissues of people and animals. It is released from animal feces. It occurs naturally in certain foods, such as some nuts and cheese. It is also one of the main chemicals responsible for bad breath and flatulence. At very high concentrations methanethiol is highly toxic and affects the central nervous system. The chemical formula for methanethiol is CH3SH; it is classified as a thiol. Methanethiol is also considered to be a weak acid, with a pKa of ~10.4. This acidic property makes it reactive with dissolved metals in aqueous solutions. The environmental chemistry of these interactions in seawater or fresh water environments such as lakes has yet to be fully investigated. -- Wikipedia .
