Dextran is a complex, branched glucan (polysaccharide made of many glucose molecules) composed of chains of varying lengths (from 3 to 2000 kilodaltons). It is used medicinally as an antithrombotic (anti-platelet), to reduce blood viscosity, and as a volume expander in hypovolaemia. The straight chain consists of α-1,6 glycosidic linkages between...

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 shie...
