In the absence of oxygen, sulfur-reducing and sulfate-reducing bacteria derive energy from oxidizing hydrogen or organic molecules by reducing elemental sulfur or sulfate to hydrogen sulfide. Other bacteria liberate hydrogen sulfide from sulfur-containing amino acids; this gives rise to the odor of rotten eggs and contributes to the odor of ...
Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl (−OH) group of an alcohol), and the word is a blend of "thio-" with "alcohol". Many thiols have strong odors resembling that of garlic , cabbage or rotten eggs.
Gaseous signaling molecules are gaseous molecules that are either synthesized internally (endogenously) in the organism, tissue or cell or are received by the organism, tissue or cell from outside (say, from the atmosphere or hydrosphere, as in the case of oxygen) and that are used to transmit chemical signals which induce certain physiological or biochemical changes in the organism, tissue or ...

When the “molecular” form of sulfur dioxide, which winemakers routinely use as an antioxidant and antimicrobial, interacted with the aluminum can it produced hydrogen sulfide — the source of ...
Its smell is reminiscent of rotten eggs or cabbage. Dimethyl sulfide (DMS), a component of the smell produced from cooking of certain vegetables, notably maize, cabbage, beetroot, and seafoods; Non-sulfur-containing odorants include the following: Methyl acrylate (MA) Ethyl acrylate (EA)
[1] [2] Sulfur springs smell of rotten eggs due to hydrogen sulfide (H 2 S), which is hazardous and sometimes deadly. It is a gas, and it usually enters the body when it is breathed in. [ 3 ] The quantities ingested in drinking water are much lower and are not considered likely to cause harm, but few studies on long-term, low-level exposure ...
