| anion | A negatively-charged ion. (09 Oct 1997) |
| anion exchange | The process by which an anion in a mobile (liquid) phase exchanges with another anion previously bound to a solid, positively charged phase, the latter being an anion exchanger. It takes place when Cl- is exchanged for OH- in desalting. The reaction is Cl- (in solution) + (OH- on anion exchanger+) → (Cl- on anion exchanger) + OH- (in solution); combined with cation exchange, NaCl is removed from solution. Anion exchange may also be used chromatographically, to separate anions, and medicinally, to remove an anion (e.g., Cl-) from gastric contents or bile acids in the intestine. (05 Mar 2000) |
| anion exchanger | Family of Integral membrane proteins that perform the exchange of chloride and bicarbonate across the plasma membrane. Best known is Band III protein of the red blood cell. (18 Nov 1997) |
| anion exchange resin | <chemistry> A resin with fixed cationic groups which is used in chromatography to separate anionic molecules. A High molecular weight, insoluble polymers that contain functional anionic groups capable of undergoing exchange reactions. These resins are used for ion exchange chromatography, as gastric antacids, hypocholesteraemics, etc. (14 Aug 2000) |
| anion gap | <biochemistry> The difference between the sum of the measured cations and anions in the plasma or serum calculated as follows: (Na + K) -(Cl + HCO3) = < 20 mmol/l. Elevated values may occur in diabetic or lactic acidosis; normal or low values occur in bicarbonate-losing metabolic acidoses. Synonym: cation-anion difference. (05 Mar 2000) |

| polyethylene glycol-superoxide dismutase | <chemical> A free radical scavenger Pharmacological action: free radical scavengers Synonym: peg-sod (26 Jun 1999) |
| polyhemoglobin-superoxide dismutase-catalase | <chemical> Intermolecularly cross-linked haemoglobin, superoxide dismutase and catalase; prevents methemoglobin formation and iron release Pharmacological action: free radical scavengers Synonym: polyhb-sod-catalase (26 Jun 1999) |
| polyoxyethylene-superoxide dismutase | <chemical> Recombinant human cu,zn superoxide dismutase with polyoxyethylene; decreases side effects of superoxide-generating antineoplastics such as adriamycin and mitomycin c Synonym: sod-poe, poe-sod, polyoxyethylene-modified superoxide dismutase (26 Jun 1999) |
| superoxide | <chemistry> Term used interchangeably for the superoxide anion or the weak acid HO2(.). Superoxide is generated both by prokaryotes and eukaryotes and is an important product of the metabolic burst of neutrophil leucocytes. A very active oxygen species, it can cause substantial damage and may be responsible for the inactivation of plasma antiproteases that contributes to the pathogenesis of emphysema. (18 Nov 1997) |
| superoxide dismutase | <enzyme> Any of a range of metalloenzymes that catalyses the formation of hydrogen peroxide and oxygen from superoxide and thus protects against superoxide induced damage. Usually has either iron or manganese as the metal cation in prokaryotes, copper or zinc in eukaryotes. (18 Nov 1997) |
| zinc superoxide | ZnO2;a yellowish white powder, insoluble in water and decomposed by acids; used in pharmaceutical preparations. Synonym: zinc superoxide. (05 Mar 2000) |
| superoxide anion | the univalent anion O2- |
