Imаge Descriptiоn The mоleculаr structure shоwn in the imаge is a trisaccharide composed of three monosaccharide units - the lower and middle sugars are the same type of sugar, and the top sugar needs to be identified. The topmost unit is a six-membered ring with a hydroxyl group in the up position attached to carbon 3, and hydroxyl groups in the down position attached to carbons 2 and 4. Furthermore, it has a hydroxymethyl group (composed of carbon 6 and an alcohol group) in the up position attached to carbon 5, which is part of the six-membered ring with an oxygen. On carbon 1, the sugar attaches to the middle sugar via a glycosidic linkage in the down position. The middle and lowest units are fructose, five-membered rings with an oxygen, a hydroxyl group in the up position attached to carbon 3, and a hydroxyl group in the down position attached to carbon 4. Furthermore, they both have a hydroxymethyl group (composed of carbon 6 and an alcohol group) in the up position attached to carbon 5. On the middle fructose, carbon 1 attaches to carbon 2 in the down position and connects to the lower fructose via a glycosidic linkage. In the up position on carbon 2 is the glycosidic linkage back to the upper sugar. On the lower fructose, a hydroxymethyl group (composed of carbon 1 and an alcohol group) is attached to carbon 2 in the down position. In the up position on carbon 2 is the glycosidic linkage back to the middle fructose. The very first ingredient listed on the label of a Fiber One chewy granola bar is chicory root extract. Chicory root is a source of the polysaccharide inulin. Inulin is classified as a fructan or a polymer of fructose similar to glucans, which are polymers of glucose (starches and cellulose). Inulin consists of fructose units joined together in a linear polymer structure.  One end of the polymer is modified by the addition of a different sugar residue. The trisaccharide structure forming the modified end is shown in the figure above and is known as kestose.  Type your response to the following prompts in the text box below.  Identify the sugar residue added to the fructose dimer, the nature of the glycosidic bond or linkage that attaches it to the fructose dimer, and the nature of the glycosidic linkage connecting the two fructose units. (3 pts.) Added sugar (full descriptive name): Bond between added sugar and Fru dimer: Fru-Fru bond: Is kestose classified as a reducing sugar? Define reducing sugar and briefly explain why or why not.  (2 pts.) Will kestose display mutarotation? Define mutarotation and briefly explain why or why not.  (2 pts.) Other significant ingredients of the Fiber One bar include high maltose corn syrup and maltodextrin. Maltodextrin is a mixture of oligosaccharides with the same structure as amylose that ranges from three to nineteen sugar units in length. Identify the sugar residues that make up the maltodextrins and the type of glycosidic linkage that connects them together to form a maltodextrin.  (2 pts.) Describe the specific structural differences between amylose and amylopectin?  (2 pts.)
