Dextran - Wikipedia
Dextran is a complex branched glucan (polysaccharide derived from the condensation of glucose), originally derived from wine. IUPAC defines dextrans as "Branched poly-α-d-glucosides of microbial origin having glycosidic bonds predominantly C-1 → C-6". [1] Dextran chains are of varying lengths (from 3 to 2000 kilodaltons).

Dextran is used as the restoration of blood mass during surgical interventions if there is hypovolemia due to trauma or dehydration. It is as well used after the presence of hemorrhage in cases of blood loss to a level inferior to 15% of the blood mass, if compatibility test cannot be completed or when blood lots need to be tested for pathogen ...

2021年7月1日 · Dextran is composed of a linear chain of d-glucoses linked by α- (1→6) bonds, with possible branches of d-glucoses linked by α- (1→4), α- (1→3), or α- (1→2) bonds, which can be low ...
Dextran - an overview | ScienceDirect Topics
Dextran is a complex branched glucan composed of α-(1 → 6) linked D- glucopyranosyl backbone modified with α(1 → 2), α(1 → 3) or α(1 → 4) branches of variable lengths (from 3 to 2000 kDa). Synthesized from sucrose by lactic acid bacteria (Streptococcus mutans, Leuconostoc mesenteroides), it is present in the dental plaque.
Dextran Structure | Pharmacosmos Dextran
Dextran Structure. Dextran is an α-D-1,6-glucose-linked glucan with side-chains 1-3 linked to the backbone units of the Dextran biopolymer. The degree of branching is approximately 5% in native (unfractionated) dextran and decreases with decreasing molecular weight. The branches are mostly 1-2 glucose units long.

Dextran has the basic chemical formula H (C 6 H 10 O 5) n OH (Fig. 31.11; Diana, Humberto, & Jorge, 2019). It is an α-type glucan produced from sucrose by the action of the bacterial extracellular enzyme dextransucrase.
Iron Dextran - PubChem
Iron Dextran is a colloidal solution containing ferric oxyhydroxide complexed with polymerized dextran, used as a form of parenteral iron-replacement therapy. Upon administration and absorption, the iron dextran complex is removed from plasma by the reticuloendothelial system which cleaves it into the components iron and dextran; ferric iron ...

2024年10月31日 · Dextran is a polysaccharide composed of glucose molecules used as an antithrombotic to reduce blood viscosity and as a volume expander in anemia. Studies show that it inhibits the mannose receptor-med iated clearance of tissue-type plasminogen activator (t-PA). Definition. dextran: A glutinous glucose polymerproduced by certain bacteria.
Dextran - an overview | ScienceDirect Topics
Dextran is a complex, branched polysaccharide made of many glucose molecules joined into chains of varying lengths. The straight chain consists of α (1→6) glycosidic linkages between glucose molecules, while branches begin from α (1→3) linkages (and in some cases, α1→2 and α1→4 linkages as well).
