| sodium hydrogen sulfite | NaHSO3;acid sodium sulfite, used in gastric and intestinal fermentation, externally in the treatment of parasitic diseases, and as an antioxidant in certain injections (s. Metabisulfite). Synonym: sodium hydrogen sulfite, sodium pyrosulfite. (05 Mar 2000) |
| sodium sulfite | Na2SO3-7H2O;has been used for the relief of intestinal fermentation, and externally for aphthous stomatitis. (05 Mar 2000) |
| sulfite | A salt of sulfurous acid; elevated in cases of molybdenum cofactor deficiency. Sulfite dehydrogenase, an oxidoreductase catalyzing the reaction of sulfite with 2 ferricytochrome c and water to sulfate and 2-ferrocytochrome c. Sulfite oxidase, a liver oxidoreductase (haemoprotein) catalyzing the reaction of inorganic sulfite ion with O2 and water to produce sulfate ion and H2O2; a lower activity of this enzyme is observed in cases of molybdenum cofactor deficiency. Sulfite reductase, oxidoreductase catalyzing reduction of sulfite to H2S using some reduced acceptor. (05 Mar 2000) |
| sulfite oxidases | <enzyme> A molybdohemoprotein which catalyses the terminal reaction in the oxidative degradation of sulfur-containing amino acids with the formation of a sulfate. Cytochrome c, ferricyanide and molecular oxygen can act as acceptors. A deficiency is manifested by brain damage and mental deterioration. Utilises ferricytochrome c as acceptor. Uses molecular oxygen. Registry number: EC 1.8.3.1 (12 Dec 1998) |
| sulfite reductases | <enzyme> Hydrogen sulfide:(acceptor) oxidoreductases. Enzymes which reversibly catalyze the oxidation of hydrogen sulfide in the presence of various acceptors to sulfite and a reduced acceptor. Utilises NADP+ as the acceptor. Utilises oxidised ferredoxin as acceptor and EC 1.8.99.1 will utilise a variety of acceptors. Registry number: EC 1.8.- (12 Dec 1998) |
| exsiccated sodium sulfite | Anhydrous sodium sulfite, used as a preservative in pharmaceutical preparations. (05 Mar 2000) |
| aluminum bismuth oxide | A gastric antacid. Synonym: aluminum bismuth oxide. (05 Mar 2000) |
| bismuth | <chemistry> One of the elements; a metal of a reddish white colour, crystallizing in rhombohedrons. It is somewhat harder than lead, and rather brittle; masses show broad cleavage surfaces when broken across. It melts at 507 deg Fahr, being easily fused in the flame of a candle. It is found in a native state, and as a constituent of some minerals. Specific gravity 9.8. Atomic weight 207.5. Symbol Bi. Chemically, bismuth (with arsenic and antimony is intermediate between the metals and nonmetals; it is used in thermo-electric piles, and as an alloy with lead and tin in the fusible alloy or metal. Bismuth is the most diamagnetic substance known. Bismuth glance, bismuth sulphide; bismuthinite. Bismuth ocher, a native bismuth oxide; bismite. Origin: Ger. Bismuth, wismuth: cf. F. Bismuth.
