| sulfur compounds | Inorganic or organic compounds that contain sulfur as an integral part of the molecule. (12 Dec 1998) |
|---|---|
| sulfur dioxide | <chemical> A highly toxic, colourless, nonflammable gas. It is used as a pharmaceutical aid and antioxidant. It is also an environmental air pollutant. Pharmacological action: air pollutants, environmental, antioxidants, pharmaceutic aid. Chemical name: Sulfur dioxide (12 Dec 1998) |
| sulfur-ferric ion oxidoreductase | <enzyme> From thiobacillus ferrooxidans; catalyses the production of sulfite and fe(2+) from elemental sulfur and fe(3+) Registry number: EC 1.8.99.- Synonym: sf oxidoreductase, sulfite-ferric ion oxidoreductase (26 Jun 1999) |
| sulfur hexafluoride | <chemical> Sulfur hexafluoride. An inert gas used mainly as a test gas in respiratory physiology. Other uses include its injection in vitreoretinal surgery to restore the vitreous chamber and as a tracer in monitoring the dispersion and deposition of air pollutants. Chemical name: Sulfur fluoride (SF6), (OC-6-11)- (12 Dec 1998) |
| sulfur iodide | Has been used in the treatment of certain skin diseases. (05 Mar 2000) |
| sulfur isotopes | Stable sulfur atoms that have the same atomic number as the element sulfur, but differ in atomic weight. S-33, 34, and 36 are stable sulfur isotopes. (12 Dec 1998) |
| sulfur mustard | <chemical> 1,1'-thiobis(2-chloroethane). Severe irritant and vesicant of skin, eyes, and lungs. It may cause blindness and lethal lung oedema and was formerly used as a war gas. The substance has been proposed as a cytostatic and for treatment of psoriasis. It has been listed as a known carcinogen in the fourth annual report on carcinogens (ntp-85-002, 1985) (merck, 11th ed). Pharmacological action: carcinogens, chemical warfare agents, dermatologic agents. Chemical name: Ethane, 1,1'-thiobis(2-chloro- (12 Dec 1998) |
| sulfur oxides | Inorganic oxides of sulfur. (12 Dec 1998) |
| sulfur oxygenase reductase | <enzyme> From desulfurolobus ambivalens; in the presence of oxygen but not under a hydrogen atmosphere simultaneously produces sulfite, thiosulfate, and hydrogen sulfide from sulfur; inhibited by sulfhydryl reagents, fad, ferrous and ferric ions Registry number: EC 1.8.- Synonym: sor gene product (sulfur oxygenase reductase) (26 Jun 1999) |
| sulfur radioisotopes | Unstable isotopes of sulfur that decay or disintegrate spontaneously emitting radiation. S 29-31, 35, 37, and 38 are radioactive sulfur isotopes. (12 Dec 1998) |
| sulfur-reducing bacteria | A group of gram-negative, anaerobic bacteria that is able to oxidise acetate completely to carbon dioxide using elemental sulfur as the electron acceptor. (12 Dec 1998) |
| sulfur trioxide | SO3;forms sulfuric acid, H2SO4, by its reaction with water. Synonym: sulfuric oxide. (05 Mar 2000) |
| sulfur water | A water containing hydrogen sulfide or the metallic sulfides. (05 Mar 2000) |
| iron-sulfur proteins | A group of proteins possessing only the iron-sulfur complex as the prosthetic group. These proteins participate in all major pathways of electron transport: photosynthesis, respiration, hydroxylation and bacterial hydrogen and nitrogen fixation. (12 Dec 1998) |
| technetium tc 99m sulfur colloid | <chemical> A gamma-emitting radionuclide imaging agent used for the diagnosis of diseases in many tissues, particularly in the gastrointestinal system, liver, and spleen. Pharmacological action: radiopharmaceuticals. (12 Dec 1998) |
