4. The structure of a branched polysaccharide consisting of D-glucose residues is shown below. (8 pts.) CH2OH CH2OH CH2OH O OH OH OH HO OH OH OH CH2 CH?OH CH2OH CH?OH O O OH OH OH OH HO OH OH OH OH OH (a) Circle all of the anomeric carbons in the polysaccharide. Box the carbons that determine the D or L configuration of the glucose residues. Is this molecule a reducing or nonreducing sugar? (b) How many reducing and nonreducing ends would be present in a molecule with a similar structure if it had 155 glucose residues and 10 a(1?6) branch points? (c) Carbohydrates can be treated with dimethyl sulfate, which adds a methyl group to free hydroxyl groups. If the polysaccharide above is treated with dimethyl sulfate and then cleaved to hydrolyze all of its glycosidic bonds, draw the structures of the four different types of methylated glucose molecules that would be produced.
