In the structure in the picture, the monosaccharide units (alpha-D-galactopyranosyl and beta-D-allopyranose) are linked via alpha-1->3 glycosidic bond. Then, the formed disaccharide units are linked via beta-1->4 glycosidic bond. Then, an Oligosaccharide is formed which has 10 monosaccharide units, meaning that it contains 5 disaccharide units. Question: Is this oligosaccharide a good substrate for glycolysis? Provide two reasons for your answer.
