###### Question:

Sephadex& is a commercially produced branched homopolysaccharide. It contains alpha- glycosidic linkages at carbons 2, 3, 4, and 6. The degree of cross-linking at those carbons can be controlled, yielding holes within the polymer of known size. 2. a. What lab method (which we learned about in class) can use such a molecule? b. Explain how this method works. c. What is the monosaccharide from which Sephadex® is made? d. Draw the disaccharide formed when 2 units of this monomer are linked by an a(14) glycosidic bond.
