Pharmaceutical grade Dextran 40/70/84 CAS 9004-54-0
Dextran is a complex, branched glucan (polysaccharide made of many glucose molecules) composed of chains of varying lengths (from3 to 2000 kilodaltons). It is used medicinally as an antithrombotic (anti-platelet), to reduce blood viscosity, and as a volume expander in anemia.
The straight chain consists of α-1,6 glycosidic linkages between glucose molecules, while branches begin from α-1,3 linkages. (For information on the numbering of carbon atoms in glucose, see the glucose article.) Dextran is synthesized from sucrose by certain lactic-acid bacteria, the best-known being Leuconostoc mesenteroides and Streptococcus mutans. Dental plaque is rich in dextrans.
Dextran is also formed by the lactic acid bacterium Lactobacillus brevis to create the crystals of tibicos, a water kefir fermented beverage which supposedly has some health benefits.
Function and Application
Medicine for blood volume expansion, improved plasma colloid osmotic pressure, increase of plasma volume and maintain blood pressure, prevent shock, can prevent the red blood cell and platelet aggregation, reduce blood viscosity, which has the effect of improving microcirculation.
