An oligosaccharide is a repeating unit of a-D-galactopyranosyl-(a-1 >3)-allopyranoside. Each disaccharide unit is linked via B-1 --->4 glycosidic bond. The oligosaccharide has 10 monosaccharide residues. Required: Is this oligosaccharide a good substrate for glycolysis? Why or why not? Provide two reasons and discuss corn prehensively.

The fructose in honey is mainly in the β-D-pyranose form. This is oneof the sweetest carbohydrates known, about twice as sweet as glucose; the β-D-furanose form of fructose is much less sweet. The sweetness of honey gradually decreases at a high temperature. Also, high-fructose corn syrup (a commercial product in which much of the glucose in corn syrup is converted to fructose) is used for sweetening cold but not hot drinks. What chemical property of fructose could account for both these observations?
