Cylinder of methanethiol gas. Methanethiol is mainly used to produce the essential amino acid methionine, which is used as a dietary component in poultry and animal feed. [10] Methanethiol is also used in the plastic industry as a moderator for free-radical polymerizations [10] and as a precursor in the manufacture of pesticides.
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
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 ...
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
In enzymology, a methanethiol oxidase (EC 1.8.3.4) is an enzyme that catalyzes the chemical reaction. methanethiol + O 2 + H 2 O formaldehyde + hydrogen sulfide + H 2 O 2. The 3 substrates of this enzyme are methanethiol, O 2, and H 2 O, whereas its 3 products are formaldehyde, hydrogen sulfide, and H 2 O 2.
The by-products are dimethyl sulfide ((CH 3) 2 S), carbon monoxide (CO), carbon dioxide (CO 2) and—when triethylamine is used as base—triethylammonium chloride (Et 3 NHCl). Of the volatile by-products, dimethyl sulfide has a strong, pervasive odour and carbon monoxide is acutely toxic, so the reaction and the work-up needs to be performed ...
