| activated charcoal | <drug> A type of carbon produced through exposing a source material such as wood or bone to very high temperatures in the presence of steam, air or carbon monoxide. Activated carbon is very good at removing (adsorbing) contaminants and is used in water filters, to decolour solutions and is sometimes administered to poisoning victims. (15 Jan 1998) |

| activated choline | An intermediate in the formation of phosphatidylcholine (lecithin); formed by the action of cytidine 5'-triphosphate on phosphocholine, linking the choline phosphate group to the alpha-phosphate of the cytidine 5'-triphosphate to give a pyrophosphate. Synonym: activated choline, cytidine diphosphate choline. (05 Mar 2000) |
| activated complex | <chemistry> State of highest energy during a reaction. When reactants form the activated complex, bond breaking and bond formation is occurring. Synonym: transition state. (09 Jan 1998) |
| activated fatty acid | A fatty acyl-coenzyme A thiol ester. (05 Mar 2000) |
| activated glucose | A nucleoside diphosphoglucose such as UDP glucose. (05 Mar 2000) |
| activated macrophage | A mature macrophage, in an active metabolic state, that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. Synonym: armed macrophage. (05 Mar 2000) |
| activated resin | Autopolymerizing resin, any resin that can be polymerised by chemical catalysis rather than by the application of heat; used in dentistry for dental restoration, denture repair, and impression trays. Synonym: activated resin, cold cure resin, cold-curing resin, quick cure resin, self-curing resin. (05 Mar 2000) |
| activated sludge | See: activated sludge method. (05 Mar 2000) |
| activated sludge method | A method of sewage disposal in which the sewage is treated with 15% bacterially active, liquid sludge, which is produced by repeated vigorous aeration of fresh sewage to form floccules or sediment; when this flocculation process is complete, the resulting activated sludge contains large numbers of bacteria, together with yeasts, molds, and protozoa, which actively effect the oxidation of organic compounds; this mixture is piped to a sedimentation tank, the effluent from which is completely treated sewage. (05 Mar 2000) |
| activated sludge process | <procedure> A method of treating sewage and wastewater through microbial oxidation. Sewage previously treated in settling tanks is aerated to encourage the growth of nonpathogenic aerobic microorganisms (bacteria, yeasts, moulds and protozoans) which break the organic matter down into carbon dioxide, water and simple salts. After this activated sludge is produced, the wastewater undergoes further processing through anaerobic digestion, filtering and chlorination. (29 Dec 1997) |
| activated state | <chemistry, radiobiology> An atom or nucleus which possesses more energy than its ground state energy. (16 Dec 1997) |
| AMP-activated protein kinase kinase | <enzyme> An endogenous kinase kinase; reactivates the inactive form of AMP-activated protein kinase (AMP-pk); phosphorylates the 63-kD subunit of AMP-pk Registry number: EC 2.7.1.- Synonym: AMP-pk reactivator, hmg CoA reductase kinase kinase (26 Jun 1999) |
| basic polypeptide-activated protein kinase | <enzyme> Requires mn2+ for its activity; from bombyx mori; does not require cyclicamp, cyclicgmp or ca Registry number: EC 2.7.1.- Synonym: ba kinase (26 Jun 1999) |
| calcium-calmodulin-activated histone 3 arginine kinase | <enzyme> From nuclear extracts of dividing and quiescent rat heart endothelial cells; represents a new class of ca-cam-dependent kinases which phosphorylate arg Registry number: EC 2.7.10.- Synonym: ca(2+)-calmodulin-activated histone 3 arg kinase, ca-cam h3 kinase (26 Jun 1999) |
| Receptors for activated C Kinase | Synonym for endosome. (18 Nov 1997) |
