| SST | sodium sulfite titration; somatostatin |
| 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) |
|---|
| amino acid oxidases | Flavoenzymes oxidizing, with O2 and H20, either l-or d-amino acids specifically, to the corresponding 2-keto acids, NH3 and H2O2. Compare: amino acid dehydrogenases, yellow enzyme. (05 Mar 2000) |
|---|---|
| mixed function oxidases | <enzyme> Catalyse the insertion of one oxygen atom of molecular oxygen into the organ substrate. Require a second substrate to donate electrons for the reduction of the second atom in the oxygen molecule to water. Registry number: EC 1.13.12. (12 Dec 1998) |
| calcium sulfite | Used as an intestinal antiseptic, and locally in the treatment of parasitic skin diseases. (05 Mar 2000) |
| 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 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) |
