Hi, Pure dextrans are linear alpha16 linked. Branched or not depends on the enzyme (dextransucrase) that has been used to synthesize it. If branching occurs this will be mostly on the alpha13. Sulfation can occur on some or all the free hydroxyls groups.

Some reviews draw it as an unbranched glucose polysaccharide with sulfates on C2, C3, and C4. Others draw it as having sulfates on C2 and C4. Yet a third group draws it as branched polysaccharide.
