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 ...
Thus, the two substrates of this enzyme are trimethylsulfonium and tetrahydrofolate, whereas its two products are dimethyl sulfide and 5-methyltetrahydrofolate. This enzyme belongs to the family of transferases , specifically those transferring one-carbon group methyltransferases.
The major volatile compounds responsible for garlic breath are allyl methyl sulfide, allyl methyl disulfide, allyl mercaptan, diallyl disulfide, dimethyl disulfide and methyl mercaptan, along with minor amounts of dimethyl selenide. [1] [2] [3] Various other sulfur compounds are also produced when allicin in garlic is broken down in the stomach ...
Medical condition Flatulence Other names Farting, breaking wind, passing gas, cutting the cheese, cutting one loose, ripping one, tooting Specialty Gastroenterology Flatulence is the expulsion of gas from the intestines via the anus, commonly referred to as farting. "Flatus" is the medical word for gas generated in the stomach or bowels. A proportion of intestinal gas may be swallowed ...

Bacteria in environments both with and without oxygen can also convert methanethiol to dimethyl sulfide (DMS), although most DMS in surface seawater is produced by a separate pathway. [6] Both DMS and methanethiol can be used by certain microbes as substrates for methanogenesis in some anaerobic soils.
The use of triphenylphosphine, thiourea, zinc dust, or dimethyl sulfide produces aldehydes or ketones. While the use of sodium borohydride produces alcohols. (R group can also be hydrogens) The use of hydrogen peroxide can produce carboxylic acids. Amine N-oxides produce aldehydes directly. [8]
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 ...
