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 (antiplatelet), to reduce blood viscosity, and as a volume expander in hypovolaemia.
The straight chain consists of α-1,6 glycosidic linkages between glucose molecules, while branches begin from α-1,3 linkages. 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.〔http://www.ncbi.nlm.nih.gov/pmc/articles/PMC422963/〕
Dextran was first discovered by Louis Pasteur as a microbial product in wine.
