| 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) |
| androgens, synthetic | Compounds obtained by chemical synthesis which possess masculinizing activities, but differ in structure from naturally occurring androgens. (12 Dec 1998) |
| vaccines, synthetic | Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified. (12 Dec 1998) |
| genes, synthetic | Biologically functional sequences of DNA chemically synthesised in vitro. (12 Dec 1998) |
| glucocorticoids, synthetic | <chemical> Synthetic chemical compounds which increase gluconeogenesis, raising the concentration of liver glycogen and blood sugar, but differ in structure from naturally occurring glucocorticoids. Pharmacological action: steroidal anti-inflammatory agents, topical anti-inflammatory agents. (12 Dec 1998) |
| resins, synthetic | Polymers of high molecular weight which at some stage are capable of being molded and then harden to form useful components. (12 Dec 1998) |
| mineralocorticoids, synthetic | Synthetic steroids that mimic the activity of the mineralocorticoids obtained from the adrenal cortex, but differ in structure from the naturally occurring mineralocorticoids. (12 Dec 1998) |
| contraceptives, oral, synthetic | Oral contraceptives which owe their effectiveness to synthetic preparations. (12 Dec 1998) |
| contraceptives, postcoital, synthetic | Postcoital contraceptives which owe their effectiveness to synthetic preparations. (12 Dec 1998) |
| progestational hormones, synthetic | Compounds obtained by chemical synthesis that possess progestational activity, but differ in structure from naturally occurring progestational hormones. (12 Dec 1998) |
| prostaglandin endoperoxides, synthetic | Synthetic compounds that are analogs of the naturally occurring prostaglandin endoperoxides and that mimic their pharmacologic and physiologic activities. They are usually more stable than the naturally occurring compounds. (12 Dec 1998) |
| prostaglandins a, synthetic | Analogs or derivatives of prostaglandin a that do not occur naturally in the body. They do not include the product of the chemical synthesis of hormonal pga. (12 Dec 1998) |
