| vinyl chloride | <chemical> A gas that has been used as an aerosol propellant and is the starting material for polyvinyl resins. Toxicity studies have shown various adverse effects, particularly the occurrence of liver neoplasms. Pharmacological action: carcinogens. Chemical name: Ethene, chloro- (12 Dec 1998) |
| cesium chloride | <chemical> Salt that yields aqueous solutions of high density. When equilibrium has been established between sedimentation and diffusion during ultracentrifugation, a linear density gradient is established in which macromolecules such as DNA band at a position corresponding to their own buoyant density. (18 Nov 1997) |
| cesium chloride gradient centrifugation | A type of density gradient centrifugation, a lab technique used to separate or purify nucleic acids. It involves putting cesium chloride and the nucleic acids into a centrifuge to be spun for hours or days. The cesium chloride forms a density gradient (highly dense at the bottom, thinnest at the top), and the different nucleic acids separate along the gradient according to their buoyancies in different densities.

| cetalkonium chloride | Benzylhexadecyldimethylammonium chloride;an antibacterial agent. (05 Mar 2000) |
| cetylpyridinium chloride | The monohydrate of the quaternary salt of pyridine and cetyl chloride; a cationic detergent with antiseptic action against nonsporulating bacteria. (05 Mar 2000) |
| mercuric chloride | <chemical> Mercury chloride (hgcl2). A highly toxic compound that volatises slightly at ordinary temperature and appreciably at 100 degrees c. It is corrosive to mucous membranes and used as a topical antiseptic and disinfectant. Pharmacological action: anti-infective agents, local, disinfectants. Chemical name: Mercury chloride (HgCl2) (12 Dec 1998) |
| mercurous chloride | HgCl;mild mercury chloride; mercury monochloride, protochloride, or subchloride; has been used as an intestinal antiseptic and laxative; replaced by safer agents. Synonym: mercurous chloride, sweet precipitate. Origin: Mediev. L., fr. G. Kalos, beutiful, + melas, black (05 Mar 2000) |
| chloride | A compound containing chlorine, at a valence of -1, as in the salts of hydrochloric acid. (05 Mar 2000) |
| chloride channel | Ion channels selective for chloride ions. Various types including ligand activated Cl channels at synapses (the GABA and glycine activated channels), as well as voltage gated Cl channels found in a variety of plant and animal cells. See: CFTR, MDR. (18 Nov 1997) |
| chloride channels | Cell membrane glycoproteins selective for chloride ions. (12 Dec 1998) |
| chloride current | Flow of chloride ions through chloride selective ion channels. (18 Nov 1997) |
| chloride depletion | Excessive loss of sodium chloride from the body in urine, sweat, etc.; a cause of secondary dehydration. Synonym: chloride depletion. Water depletion, reduction in the total volume of body water; dehydration. (05 Mar 2000) |
| chloride peroxidase | <enzyme> An enzyme that catalyses the chlorination of a range of organic molecules, forming stable carbon-chloride bonds. Chemical name: Chloride:hydrogen-peroxide oxidoreductase Registry number: EC 1.11.1.10 (12 Dec 1998) |
| chloride shift | When CO2 enters the blood from the tissues, it passes into the red blood cell and is converted by carbonate dehydratase to bicarbonate (HCO3-); HCO3- ion passes out into the plasma while Cl- migrates into the red blood cell. Reverse changes occur in the lungs when CO2 is eliminated from the blood. Synonym: Hamburger's phenomenon. (05 Mar 2000) |
