| potassium sulfocyanate | Formerly used in the treatment of essential hypertension and as a reagent in the detection of copper, iron, and silver. Synonym: potassium rhodanate, potassium sulfocyanate. (05 Mar 2000) |
|---|---|
| potassium tartrate | K2C4H4O6-1/2 H2O;a mild purgative and diuretic. Synonym: soluble tartar. (05 Mar 2000) |
| potassium thiocyanate | Formerly used in the treatment of essential hypertension and as a reagent in the detection of copper, iron, and silver. Synonym: potassium rhodanate, potassium sulfocyanate. (05 Mar 2000) |
| hydrogen-potassium-exchanging atpase | <enzyme> An enzyme isolated from the gastric mucosa that catalyses the hydrolysis of ATP coupled with the exchange of hydrogen and potassium ions across the cell wall. Chemical name: ATP phosphohydrolase (H+/K+-transporting) Registry number: EC 3.6.1.36 (12 Dec 1998) |
| 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) |
| effervescent potassium citrate | A mixture of potassium citrate, citric acid, sodium bicarbonate, and tartaric acid; used as a gastric antacid and urinary alkaliser. (05 Mar 2000) |
| Luft's potassium permanganate fixative | A fixative useful in electron microscopy for cytologic preservation of lipoprotein complexes in membranes and myelin, because of its oxidative properties. (05 Mar 2000) |
| Rambourg's chromic acid-phosphotungstic acid stain | <technique> A stain for glycoproteins, used with an electron microscope, with which ultrathin tissue sections reveal complex carbohydrates in the same locations as shown by Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| acetyl phosphate | CH3CO-OPO32-;a "high energy" phosphate that acts as an acetate donor in the metabolism of various bacteria. Synonym: acetic phosphoric anhydride. (05 Mar 2000) |
| acidulated phosphate fluoride | <chemical> Phosphoric acid, mixt. With sodium fluoride (naf). A sodium fluoride solution, paste or powder, which has been acidulated to pH 3 to 4 and buffered with a phosphate. It is used in the prevention of dental caries. Pharmacological action: fluorides, topical. Chemical name: Phosphoric acid, mixt. With sodium fluoride (NaF) (12 Dec 1998) |
| acyl dihydroxyacetone phosphate oxidoreductase | <enzyme> Forms acyl-sn-glycerol 3-phosphate; uses NADPH Registry number: EC 1.1.1.- (26 Jun 1999) |
| adenosine 3',5'-cyclic phosphate phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of adenosine 3',5'-cyclic phosphate forming 5'-AMP. A crucial step in the regulation of cellular adenosine 3',5'-cyclic phosphate levels. Inhibited by caffeine. Synonym: cAMP phosphodiesterase. (05 Mar 2000) |
