A repeating unit of -D-glucopyranosyl-(-1—->6)-allopyranoside is called an oligosaccharide. A -1 —->4 glycosidic bond connects each disaccharide unit. Make a diagram of the molecular structure. There are ten monosaccharide residues in the oligosaccharide. a. Upon the action of beta glucosidase, draw the molecular structure of all possible resulting products. Briefly explain your answer b. Draw the L-isomer of the Fisher projection of one epimer of D-glucopyranoside. Explain why this is an epimer of the monosaccharide. c. Is this oligosaccharide a good substrate for glycolysis? Why or why not? Provide two reasons and discuss comprehensively
