| sodium potassium ATPase | <enzyme> A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell and 2 potassium ions in, for each ATP hydrolysed. The sodium gradient established is used for several purposes (see facilitated diffusion, action potential), while the potassium gradient is dissipated through the potassium leak channel. Must not be confused with a sodium channel. (18 Nov 1997) |
|---|---|
| sodium-potassium-exchanging atpase | <enzyme> An enzyme that catalyses the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane atpase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients. Chemical name: ATP phosphohydrolase (sodium-potassium-transporting) Registry number: EC 3.6.1.37 (12 Dec 1998) |
| sodium-potassium pump | A membrane-bound transporter that maintains the high potassium and low sodium intracellular concentrations relative to the extracellular medium. This exchange is accomplished at the expense of cellular energy in the form of ATP. (05 Mar 2000) |
| sodium potassium tartrate | KNaC4H4O6;a mild saline cathartic, used as an ingredient in compound effervescent powders. Synonym: Rochelle salt, Seignette's salt, sodium potassium tartrate. (05 Mar 2000) |
| sodium propionate | The sodium salt of propionic acid; used for fungus infections of the skin, usually in combination with calcium propionate; used as a preservative. (05 Mar 2000) |
| sodium psylliate | The sodium salt of the liquid fatty acids of psyllium oil, prepared by dissolving the fatty acid in dilute sodium hydroxide solution; used like morrhuate sodium as a sclerosing agent in the treatment of varicose veins. (05 Mar 2000) |
| sodium pteroylglutamate | The sodium salt of folic acid; action and uses are the same as those of folic acid, but it is preferred for parenteral administration. Synonym: sodium pteroylglutamate. (05 Mar 2000) |
| sodium pump | <enzyme> A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell and 2 potassium ions in, for each ATP hydrolysed. The sodium gradient established is used for several purposes (see facilitated diffusion, action potential), while the potassium gradient is dissipated through the potassium leak channel. Must not be confused with a sodium channel. (18 Nov 1997) |
| sodium pyroborate | Na2B4O7-10H2O;used in lotions, gargles, mouthwashes, and as a detergent. Synonym: borax, sodium pyroborate, sodium tetraborate. (05 Mar 2000) |
| sodium pyrosulfite | 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 radioisotopes | Unstable isotopes of sodium that decay or disintegrate emitting radiation. Na atoms with atomic weights 20-22 and 24-26 are radioactive sodium isotopes. (12 Dec 1998) |
| sodium-responsive periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| sodium rhodanate | NaSCN;used in the management of essential hypertension. Synonym: sodium rhodanate, sodium sulfocyanate. (05 Mar 2000) |
| sodium ricinoleate | Sodium ricinate, the sodium salt of ricinoleic acid; a sclerosing agent similar in action to morrhuate sodium. (05 Mar 2000) |
| sodium salicylate | <chemical> A non-steroidal anti-inflammatory agent that is less effective than equal doses of aspirin in relieving pain and reducing fever. However, individuals who are hypersensitive to aspirin may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as aspirin, but there is less occult gastrointestinal bleeding. Pharmacological action: non-steroidal anti-inflammatory agents, cyclooxygenase inhibitors. Chemical name: Benzoic acid, 2-hydroxy-, monosodium salt (12 Dec 1998) |
