| potassium perchlorate | KClO4;occasionally used, as an alternative to a thiouracil derivative, in the control of hyperthyroidism. (05 Mar 2000) |
| potassium permanganate | <chemical> Permanganic acid (hmno4), potassium salt. A highly oxidative, water-soluble compound with purple crystals, and a sweet taste. Chemical name: Permanganic acid (HMnO4), potassium salt (12 Dec 1998) |
| potassium phosphate | K2HPO4;a mild saline cathartic and diuretic. Synonym: dibasic potassium phosphate, dipotassium phosphate. (05 Mar 2000) |
| potassium radioisotopes | Unstable isotopes of potassium that decay or disintegrate emitting radiation. K atoms with atomic weights 37, 38, 40, and 42-45 are radioactive potassium isotopes. (12 Dec 1998) |
| potassium rhodanate | 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 sodium 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) |
| potassium sparing diuretics | Diuretic agents that, unlike most diuretics, retain potassium; examples are triamterene and amiloride. Often used together with diuretics that promote the loss of both sodium and potassium. Used in hypertension and in congestive heart failure. (05 Mar 2000) |
| potassium succinate | A deliquescent powder used as a haemostatic. (05 Mar 2000) |
| potassium sulfate | K2SO4;an obsolete laxative. (05 Mar 2000) |
| 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) |
