CH 3 SH + CH 3 ONa → CH 3 SNa + CH 3 OH. The resulting thiolate anion is a strong nucleophile. It can be oxidized to dimethyl disulfide: 2CH 3 SH + [O] → CH 3 SSCH 3 + H 2 O. Further oxidation takes the disulfide to two molecules of methanesulfonic acid, which is odorless. Bleach deodorizes methanethiol in this way.
Dimethyl sulfide has a characteristic odor commonly described as cabbage-like.It becomes highly disagreeable at even quite low concentrations. Some reports claim that DMS has a low olfactory threshold that varies from 0.02 to 0.1 ppm [clarification needed] between different persons, but it has been suggested that the odor attributed to dimethyl sulfide may in fact be due to disulfides ...
One of its breakdown products is methanethiol (CH 3 SH), which is assimilated by bacteria into protein sulfur. Another volatile breakdown product is dimethyl sulfide (CH 3 SCH 3 ; DMS). There is evidence that DMS in seawater can be produced by cleavage of dissolved (extracellular) DMSP [ 7 ] [ 8 ] by the enzyme DMSP-lyase , although many non ...
This enzyme involved in methanogenesis from methylated thiols, such as methanethiol, dimethyl sulfide, and 3-S-methylmercaptopropionate. References
Dimethyl trisulfide (DMTS) is an organic chemical compound and the simplest organic trisulfide, with the chemical formula CH 3 SSSCH 3. [ 2 ] [ 3 ] It is a flammable liquid with a foul odor, which is detectable at levels as low as 1 part per trillion.
The two organic substituents are indicated by the prefixes. (CH 3) 2 S is called dimethylsulfide. Some sulfides are named by modifying the common name for the corresponding ether. For example, C 6 H 5 SCH 3 is methyl phenyl sulfide, but is more commonly called thioanisole, since its structure is related to that for anisole, C 6 H 5 OCH 3.
Dimethyl-sulfide monooxygenase (EC 1.14.13.131, dimethylsulfide monooxygenase) is an enzyme with systematic name dimethyl sulfide,NADH:oxygen oxidoreductase. [1] This enzyme catalyses the following chemical reaction. dimethyl sulfide + O 2 + NADH + H + methanethiol + formaldehyde + NAD + + H 2 O
Methanomethylovorans hollandica is a species of methylotrophic methanogen able to grow on dimethyl sulfide and methanethiol. It is the type species of its genus. It is obligately anaerobic. [1] It was the first strictly anaerobic archeaon isolated from freshwater sediments in which dimethyl sulfide is the sole source of carbon. It is not a ...
