| proton pump | Integral membrane proteins that transport protons across a membrane against a concentration gradient. This transport is driven by hydrolysis of ATP by hydrogen-transporting ATP synthase. (12 Dec 1998) |
|---|---|
| proton pump inhibitor | <pharmacology> A group of anti-ulcer medications which work by binding to H+/K+ ATPase, an enzyme which is found on the secretory surface of parietal cells. It thereby inhibits the final transport of hydrogen ions (via exchange with potasium) into the gastric lumen. Examples of proton pump inhibitors include omeprazole and lansoprazole. (27 Sep 1997) |
| membrane-bound proton-translocating PPi synthase | <enzyme> From rhodospirillum rubrum; functions as an alternative coupling factor; n,n'-dicyclohexylcarbodiimide-sensitive; catalyses the phosphorylation of pi to ppi, the hydrolysis of ppi and the concomitant translocation of proton across the plasma membrane Registry number: EC 3.6.1.- Synonym: h(+)-ppi synthase (26 Jun 1999) |
|---|---|
| proton | <physics> An elementary atomic particle with a positive charge and a mass of about 1 amu. (09 Oct 1997) |
| proton acceptor | <chemistry> A base, an anionic substance that acceptsa proton during an acid-basereaction. (09 Oct 1997) |
| proton ATPase | <enzyme> An ion pump that actively transports hydrogen ions across lipid bilayers in exchange for ATP. Major groups are the F-type ATPases, that run in reverse to synthesise ATP in bacterial, mitochondrial and chloroplast membranes (ATP synthase) and the V-type ATPases found in intracellular vesicles with an acidic lumen and on certain epithelial cells (e.g. Kidney intercalated cells). Gastric H/K ATPase is a proton ATPase. (18 Nov 1997) |
| proton donor | <chemistry> An acid, a susbstance that donates protons in an acid-base reduction reaction. (10 Jan 1998) |
| proton-motive force | Energy that is generated by the transfer of protons or electrons across an energy-transducing membrane and that can be used for chemical, osmotic, or mechanical work. Proton-motive force can be generated by a variety of phenomena including the operation of an electron transport chain, illumination of a purple membrane, and the hydrolysis of ATP by a proton atpase. (12 Dec 1998) |
| air pump | 1. <physics> A kind of pump for exhausting air from a vessel or closed space; also, a pump to condense air of force in into a closed space. 2. <engineering> A pump used to exhaust from a condenser the condensed steam, the water used for condensing, and any commingled air.

| breast pump | A suction instrument for withdrawing milk from the breast. (05 Mar 2000) |
| calcium pump | A transport protein responsible for moving calcium out of the cytoplasm. See: calcium ATPase. (18 Nov 1997) |
| calf pump | Muscular activity of calf that promotes venous flow towards the heart. (05 Mar 2000) |
| Carrel-Lindbergh pump | A perfusion device designed for use in culture of whole organs. (05 Mar 2000) |
| constant infusion pump | An electrically driven device for delivery from a reservoir of a constant, often very small, volume of solution over a prolonged period of time. (05 Mar 2000) |
| saliva pump | saliva ejector |
| hogger-pump | <chemical> The for pump in the pit. Source: Websters Dictionary (01 Mar 1998) |
| pump | An hydraulic machine, variously constructed, for raising or transferring fluids, consisting essentially of a moving piece or piston working in a hollow cylinder or other cavity, with valves properly placed for admitting or retaining the fluid as it is drawn or driven through them by the action of the piston. For various kinds of pumps, see Air pump, Chain pump, and Force pump; also, under Lifting, Plunger, Rotary, etc. Circulating pump See Well. Origin: Akin to D. Pomp, G. Pumpe, F. Pompe; of unknown origin. Source: Websters Dictionary (01 Mar 1998) |
