| glycerin suppository | A conical translucent dosage form for rectal administration intended for the relief of constipation; frequently used in young children. Contains glycerin and a stiffening agent such as sodium stearate (a soap). Action is produced by lubrication, water retention, and local irritation. (05 Mar 2000) |

| glycerinated gelatin | A preparation made of equal parts of gelatin and glycerin; a firm mass liquefying at gentle heat; it is used as a vehicle for suppositories and urethral bougies. Synonym: glycerin jelly, glycerogelatin, glycogelatin. (05 Mar 2000) |
| glycerinated tincture | A tincture made with diluted alcohol to which glycerin is added to facilitate the extraction or to preserve the preparation. (05 Mar 2000) |
| glycerination | <cell culture> Permeabilisation of the plasma membrane of cells by incubating in aqueous glycerol at low temperature. The technique was first applied to muscle which, once glycerinated, can be made to contract by adding exogenous ATP and calcium. (18 Nov 1997) |
| glycerine | <chemistry> An oily, viscous liquid, C3H5(OH)3, colourless and odorless, and with a hot, sweetish taste, existing in the natural fats and oils as the base, combined with various acids, as oleic, margaric, stearic, and palmitic. It is a triatomic alcohol, and hence is also called glycerol. See Note under Gelatin. It is obtained from fats by saponification, or, on a large scale, by the action of superheated steam. It is used as an ointment, as a solvent and vehicle for medicines, and as an adulterant in wine, beer, etc. Origin: F. Glycerine, fr. Gr. Glykeros, glykys, sweet. Cf. Glucose, Licorice.

| glycerite | <medicine> A medicinal preparation made by mixing or dissolving a substance in glycerin. Source: Websters Dictionary (01 Mar 1998) |
| glycerogelatin | A preparation made of equal parts of gelatin and glycerin; a firm mass liquefying at gentle heat; it is used as a vehicle for suppositories and urethral bougies. Synonym: glycerin jelly, glycerogelatin, glycogelatin. (05 Mar 2000) |
| glyceroketone | An obsolete term for dihydroxyacetone. (05 Mar 2000) |
| glycerokinase | <enzyme> An enzyme that catalyses the formation of glycerol 3-phosphate from ATP and glycerol. Dihydroxyacetone and l-glyceraldehyde can also act as acceptors; utp and, in the case of the yeast enzyme, itp and GTP can act as donors. It provides a way for glycerol derived from fats or glycerides to enter the glycolytic pathway. Chemical name: ATP:glycerol 3-phosphotransferase Registry number: EC 2.7.1.30 (12 Dec 1998) |
| glycerol | <biochemistry> A metabolic intermediate, but primarily of interest as the central structural component of the major classes of biological lipids, triglycerides and phosphatidyl phospholipids. Also used as a cryoprotectant. (18 Nov 1997) |
| glycerol dehydratase | <enzyme> Requires a cobamide coenzyme Registry number: EC 4.2.1.30 (26 Jun 1999) |
| glycerol kinase | <enzyme> An enzyme that catalyses the formation of glycerol 3-phosphate from ATP and glycerol. Dihydroxyacetone and l-glyceraldehyde can also act as acceptors; utp and, in the case of the yeast enzyme, itp and GTP can act as donors. It provides a way for glycerol derived from fats or glycerides to enter the glycolytic pathway. Chemical name: ATP:glycerol 3-phosphotransferase Registry number: EC 2.7.1.30 (12 Dec 1998) |
| glycerol oxidase | <enzyme> Oxidises glycerol in the presence of oxygen to glyceraldehyde and hydrogen peroxide without the requirement of any exogenous cofactors; protoheme ix and copper are in prosthetic group Registry number: EC 1.1.3.- (26 Jun 1999) |
| glycerol phosphate | The anion of a phosphoric ester of glycerol; the 3-derivative is the central component of phosphatidates (R-glycerol 3-phosphate). Synonym: glycerophosphate. (05 Mar 2000) |
| glycerol-1-phosphate dehydrogenase | <enzyme> From the archaebacterium methanobacterium thermoautotrophicum; forms the glycerophosphate which is the mirror image of that found in eubacterial and eukaryotic ether phospholipids Registry number: EC 1.1.1.- Synonym: sn-glycerol-1-phosphate - nad+ oxidoreductase, sn-g-1-p dehydrogenase (26 Jun 1999) |
