2) Consider the following disaccharide which was formed from the breakdown of a polysaccharide found inplant material.ОНGlycosidic linkage:HHOHHHНОHH.OHH.ОНOHHНОHОНa. Label the glycosidic linkage above in the following format: a/B(# → #)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 notonly 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.

Copper ions present in Benedict’s reagent react with the free end of any reducing sugars, such as glucose, when heated. Originally blue in color, these copper ions are reduced by the sugar and produce an orange-red colored precipitate. Alternatively, iodine-potassium iodide (IKI) may also be used when working with starch. IKI contains special tri-iodine ions which interact with the coiled structure of a starch polymer. Prior to a reaction, the IKI displays a yellow-brown color; however, after reacting with starch, a dark purple or black color is presented. The molecule pictured below produced a blue color when tested with Benedict’s reagent, a yellow color when tested with IKI, and a violet color when tested with Biuret reagent. Based on the structure shown below and these chemical results, what kind of biomolecule is this?
Although the first two carbons of fructose and glucose are identical in structure to DHAP and GADP (from glycolysis), DHAP and GADP equilibriate on their in solution to favor the ketone over the aldehyde, while fructose and glucose do not. Why? a)The larger size of the molecule sterically hinders the isomerization b)The larger sugars have more OH groups which hydrogen bond and disrupt isomerization c)The larger sugars cyclize, and there is no carbonyl to isomerize in the cyclic form d)The larger sugars cyclize, and in the cyclic form the hydrogen bonding is very strong e)The larger sugars are less soluble in water than the smaller sugars
