Questions

The very first ingredient listed оn the lаbel оf а Fiber One chewy grаnоla 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).  However, one end of this polysaccharide 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.  a. Identify the added sugar residue and the nature of the glycosidic bond or linkage that attaches it to the fructose dimer and the nature of the glycosidic linage connecting the two fructose units. (2 pts.) Added sugar: Bond between the added sugar and Fru dimer: Fru-Fru bond b. Is kestose classified as a reducing sugar? Briefly explain why or why not.  (2 pts.) c.  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 ranging from three to nineteen glucose 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.)
