| CDPC | cytidine diphosphate choline |
|---|---|
| CGP | N-carbobenzoxy-glycyl-L-phenylalanine; chorionic growth hormone-prolactin; choline glycerophosphatid... |
| Ch | chest; Chido [antibody]; chief; child; choline; Christchurch [syndrome]; chromosome |
| ChA | choline acetylase |
| ChAC | choline acetyltransferase |
| choline phosphokinase | <enzyme> An enzyme that is active in the first step of choline phosphoglyceride (lecithin) biosynthesis by catalyzing the phosphorylation of choline to phosphorylcholine in the presence of ATP. Ethanolamine and its methyl and ethyl derivatives can also act as acceptors. Chemical name: ATP:choline phosphotransferase Registry number: EC 2.7.1.32 (12 Dec 1998) |
|---|---|
| choline salicylate | Choline salt of salicyclic acid, an analgesic and antipyretic (because of the salicylate moiety). (05 Mar 2000) |
| choline theophyllinate | A true salt of theophylline; it has mild diuretic, myocardial stimulating vasodilator, and bronchodilator actions, with the same uses as theophylline, but is better absorbed and less irritating. Synonym: choline theophyllinate. (05 Mar 2000) |
| cytidine diphosphate choline | <chemical> Donor of choline in biosynthesis of choline-containing phosphoglycerides. Pharmacological action: nootropic agents. Chemical name: Cytidine 5'-(trihydrogen diphosphate), P'-(2-(trimethylammonio)ethyl) ester, inner salt (12 Dec 1998) |
| activated acetaldehyde | The activated form of acetaldehyde that is formed during the decarboxylation of active pyruvate. Formed in alcohol fermentation and in carbohydrate metabolism. Synonym: a-hydroxyethylthiamin pyrophosphate. (05 Mar 2000) |
| activated amino acid | The product formed by the condensation of the acyl radical of an amino acid and adenosine 5'-monophosphate (originally in the form of adenosine 5'-triphosphate, with elimination of a pyrophosphoric group). Formed in the first step of protein biosynthesis. Synonym: activated amino acid. (05 Mar 2000) |
| activated atom | An atom possessing more than normal energy as a result of input of energy. See: excited state. Synonym: excited atom. (05 Mar 2000) |
| activated carboxylic acid | Derivative of a carboxyl group that is more susceptible to nucleophilic attack than a free carboxyl group; e.g., acid anhydrides, thioesters. (05 Mar 2000) |
| 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 clotting time | The most common test used for coagulation time in cardiovascular surgery. (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 partial thromboplastin time | The time needed for plasma to form a fibrin clot following the addition of calcium and a phospholipid reagent; used to evaluate the intrinsic clotting system. (05 Mar 2000) |
