| glycerophosphate | 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) |
|---|---|
| glycerophosphate permease | <chemical> Synonym: sn-glycerol-3-phosphate permease, glpt protein (26 Jun 1999) |
| glycerophosphate shuttle | A mechanism for the transfer of reducing equivalents from the cytosol into the mitochondria; NADH is used to synthesise glycerol 3-phosphate in the cytosol; this compound is then transported into the mitochondria where it is converted to dihydroxyacetone phosphate (DHAP) using FAD; DHAP then returns to the cytosol to complete the cycle; found in brain tissue, brown adipose tissue, and white muscle. (05 Mar 2000) |
| glycerophosphocholine | HOCH2-CHOH-CH2-OP(O2H)&mdas h;OCH2CH2-[N(CH3)3]+;a component of phosphatidylcholines (lecithins), in which the two OH's of glycerophosphocholine are esterified with fatty acids. Synonym: glycerophosphorylcholine. (05 Mar 2000) |
| glycerophosphocholine cholinephosphodiesterase | <enzyme> Catalyses the conversion of sn-glycero-3-phosphocholine and h2o to glycerol and choline phosphate Registry number: EC 3.1.4.38 Synonym: gpc choline phosphodiesterase (26 Jun 1999) |
| glycerophosphodiester phosphodiesterase | <enzyme> E coli enzyme; acts on variety of substrates to give glycerol-3-phosphate plus an alcohol, such as ethanolamine, choline, glycerol or glycerophosphoglycerol Registry number: EC 3.1.4.46 Synonym: gpde-phosphodiesterase, glycerophosphosphoryl diester phosphodiesterase (26 Jun 1999) |
| glycerophospholipid | <biochemistry> An amphipathic lipid that has a glycerol backbone. (09 Oct 1997) |

| glycerulose | <chemical> 1,3-dihydroxy-2-propanone. A ketotriose compound. Its addition to blood preservation solutions results in better maintenance of 2,3-diphosphoglycerate levels during storage. It is readily phosphorylated to dihydroxyacetone phosphate by triokinase in erythrocytes. In combination with naphthoquinones it acts as a sunscreening agent. Chemical name: 2-Propanone, 1,3-dihydroxy- (12 Dec 1998) |
| glyceryl | <chemistry> A compound radical, C3H5, regarded as the essential radical of glycerin. It is metameric with allyl. Synonym: propenyl. Origin: Glycerin + -yl. Source: Websters Dictionary (01 Mar 1998) |
| glyceryl alcohol | <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) |
| glyceryl borate | A soft mass obtained by heating glycerin and boric acid; an obsolete antiseptic, usually used mixed with equal parts of glycerin, constituting glycerite. Synonym: boroglycerol, glyceryl borate. (05 Mar 2000) |
| glyceryl ethers | Compounds in which one or more of the three hydroxyl groups of glycerol are in ethereal linkage with a saturated or unsaturated aliphatic alcohol; one or two of the hydroxyl groups of glycerol may be esterified. These compounds have been found in various animal tissue. (12 Dec 1998) |
