<unk>  is a complex branched glucan (polysaccharide derived from the condensation of glucose), originally derived from wine. IUPAC defines<unk> s as "Branched poly-α-d-glucosides of microbial origin having glycosidic bonds predominantly C-1 → C-6".<unk>  chains are of varying lengths (from 3 to 2000 kilodaltons). The polymer main chain consists of α-1,6 glycosidic linkages between glucose monomers, with branches from α-1,3 linkages. This characteristic branching distinguishes a<unk>  from a<unk> , which is a straight chain glucose polymer tethered by α-1,4 or α-1,6 linkages.
