Dextrans, which are polysaccharides found in dental plaque, are primarily composed of what type of linkage between D-glucose units?

Correct answer: alpha 1 to 6

Explanation

Dextrans are bacterial and yeast homopolysaccharides that are structurally distinct from starch, glycogen, and cellulose. Their main chain consists of D-glucose units joined by (alpha 1 to 6) glycosidic bonds.
