| animal dextran | <biochemistry> Branched polymer of D glucose (mostly _(1-4) linked, but some _(1-6) at branch points). Size range very variable, up to 10exp5 glucose units. Major short term storage polymer of animal cells and is particularly abundant in the liver and to a lesser extent in muscle. In the electron microscope glycogen has a characteristic asterisk or star appearance. (18 Nov 1997) |
|---|---|
| blue dextran | High molecular weight dextran containing a blue chlorotriazine dye, Cibacron Blue; used to measure the void volumes in gel filtration columns. (05 Mar 2000) |
| deae-dextran | <chemical> Diethylaminoethyldextran. Used as a support for ion-exchange chromatography. Chemical name: Dextran, 2-(diethylamino)ethyl ether (12 Dec 1998) |
| dextran | High molecular weight polysaccharides synthesised by some micro organisms. Consist of D glucose linked by _ 1,6 bonds (and a few _ 1,3 and _ 1,4 bonds). Dextran 75 (average molecular weight 75 kD) has a colloid osmotic pressure similar to blood plasma, so dextran 75 solutions are used clinically as plasma expanders. They will also cause charge shielding and at the right concentrations induce flocculation of red cells, a trick that is used in preparing leucocyte rich plasma for white cell purification in the laboratory. Cross linked dextran is the basis for Sephadex. Commercially derived from strains of Leuconostoc mesenteroides. (18 Nov 1997) |
| dextran 110 | Dextran (average MW 110,000) available as 5% solution in water or saline solution; used as a plasma volume expander. (05 Mar 2000) |
| dextran 40 | Dextran (average MW 40,000) used as a plasma volume expander and blood flow adjuvant. (05 Mar 2000) |
| dextran 70 | Dextran (average MW 70,000) used as a plasma volume expander. (05 Mar 2000) |
| dextran 75 | Dextran (average MW 75,000) used as a plasma volume expander. (05 Mar 2000) |
| dextran sulfate | <chemical> Long-chain polymer of glucose containing 17-20% sulfur. It has been used as an anticoagulant and also has been shown to inhibit the binding of HIV-1 to CD4+ T-lymphocytes. It is commonly used as both an experimental and clinical laboratory reagent and has been investigated for use as an antiviral agent, in the treatment of hypolipidemia, and for the prevention of free radical damage, among other applications. Pharmacological action: anticoagulant, antiviral agents, indicators and reagents, plasma substitutes. Chemical name: Dextran, hydrogen sulfate (12 Dec 1998) |
| dextrin-dextran transglucosidase | A glucosyltransferase transferring 1,4-alpha-d-glucosyl residues, thus catalyzing the synthesis of dextrans (with 1,6 links between monosaccharide units) from dextrins (with 1,4 links) by glucose transfer. Synonym: dextrin-dextran transglucosidase, dextrin 6-glucosyltransferase. (05 Mar 2000) |
| iron-dextran complex | <chemical> Iron dextran. A complex of ferric oxyhydroxide with dextrans of 5000 to 7000 daltons in a viscous solution containing 50 mg/ml of iron. It is supplied as a parenteral preparation and is used as a haematinic. (goodman and gilman's the pharmacological basis of therapeutics, 8th ed, p1292) Pharmacological action: haematinics. Chemical name: Iron dextran (12 Dec 1998) |
| Rambourg's chromic acid-phosphotungstic acid stain | <technique> A stain for glycoproteins, used with an electron microscope, with which ultrathin tissue sections reveal complex carbohydrates in the same locations as shown by Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| a1-acid glycoprotein | <biology> Plasma protein of mammals and birds, 38% carbohydrate. In humans a single chain glycoprotein of 39 kD. Increased levels are associated with inflammation, pregnancy and various diseases. (18 Nov 1997) |
| abscisic acid | <biochemistry> A lipid hormone that inhibits cell growth in plants, it is associated with fruit drop, leaf death and seed dormancy. It is synthesised in the plastids from carotenoids. This hormone helps plants deal with water loss, and its effects can be reversed with gibberellins. (06 May 1997) |
| abscisic acid 8'-hydroxylase | <enzyme> Catalyses conversion of abscisic acid to 8'-hydroxyabscisic acid, which rearranges to phaseic acid Registry number: EC 1.14.99.- Synonym: aba 8'-hydroxylase (26 Jun 1999) |
