| anionic detergent | Detergents in which the hydrophilic funtion is fulfilled by an anionic grouping. Fatty acids are the best known natural products in this class, but it is doubtful if they have a specific detergent function in any biological system. The important synthetic species are aliphatic sulphate esters, for example sodium dodecyl sulphate (SDS or SLS). (18 Nov 1997) |

| nonionic detergent | <chemistry> Detergent in which the hydrophilic head group is uncharged. In practice hydrophilicity is usually conferred by OH groups. Examples are the polyoxyethylene p t octyl phenols known as Tritons and octyl glucoside. Nonionic detergents can be used to solubilise intrinsic membrane proteins with less tendency to denature them than charged detergents. They do not usually cause disassembly of structures such as microfilaments and microtubules that depend on protein protein interactions. (18 Nov 1997) |
| detergent | <chemistry> An agent which purifies or cleanses. <cell biology> Amphipathic, surface active, molecules with polar (water soluble) and nonpolar hydrophobic) domains. They bind strongly to hydrophobic molecules or molecular domains to confer water solubility. Examples include: sodium dodecyl sulphate, fatty acid salts, the Triton family, octyl glycoside. Origin: L. Detergere = to cleanse (18 Nov 1997) |
| zwitterionic detergent | Detergents that are zwitterionic; often used as surfactants and in the release of proteins from biomembranes. Synonym: zwitterionic detergent. Origin: zwitterion + detergent (05 Mar 2000) |
| non-ionic contrast media | <radiology> A class of radiographic contrast media which do not ionise in solution, thereby decreasing effective osmolarity and toxicity. (05 Mar 2000) |
| ionic | Relating to an ion. (05 Mar 2000) |
| ionic coupling | <chemistry> The same as electrical coupling. (18 Nov 1997) |
| ionic medication | Movement of ions as a result of an applied electric field. For example the delivery of a charged molecule from the end of a micropipette without hydraulic flow. (18 Nov 1997) |
| ionic strength | Symbolised as g/2 or I and set equal to 0.5σmizi2, where mi equals the molar concentration and zi the charge of each ion present in solution; if molar concentrations (ci) are used instead of molality (and the solution is dilute), then I == 0.5(1/ρo)σcizi2 where ρo is the density of the solvent; a number of biochemically important events (e.g., protein solubility and rates of enzyme action) vary with the ionic strength of a solution.
