2) Consider the following disaccharide which was formed from the breakdown of a polysaccharide found in plant material. OH Glycosidic linkage: H H OH H НО H H. OH H ОН H НО НО H ОН a. Label the glycosidic linkage above in the following format: a/ßB(# → #) b. Would you expect this disaccharide to have been formed from amylose or amylopectin? c. Describe at least two chemical tests that would give insight into the structure of this disaccharide, assuming you've isolated it and wanted to elucidate the structure from scratch. Include detail on not only the tests you would use but what results you would expect to get given the structure above. Assume you can analyze the structure of any monosaccharide you get from your chemical tests.

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.
