Common NameDimethyl sulfide
DescriptionDimethylsulfide is the predominant volatile sulfur compound (VSC) in breadth malodor, a metabolite of suplatast tosilate (a dimethylsulphonium compound for the treatment of asthma) in patients that regularly take that medication. (PMID 14628896 ). Dimethylsulfide is a sulfur containing organic chemical compound with a disagreeable odor. In vapor form it is produced by cooking of certain vegetables, notably corn and cabbage, and seafood. It is also an indication of bacterial infection in malt production and brewing. It is a breakdown product of dimethylsulfoniopropionate, and is also produced by the bacterial metabolism of methanethiol. Dimethylsulfide in concentrated liquid form is insoluble and a flammable. This is a microbial metabolite that can be found in Bradyrhizobium, Cyanothece, Escherichia, Pseudomonas and Rhizobiaceae (PMID:25807229 ).
