Starch reducing end
WebbStarch as a non-reducing sugar – It takes more than one hemiacetal “needle” in a haystack of “acetals” to give a positive sugar-reduction test. As a result, polysaccharides are not classified as reducing sugars. Starch, for example, results in a negative test. Starch and sucrose are both blue, indicating that they are non-reducing sugars. WebbHow many non-reducing ends does the molecule have? How many non-reducing ends would a glycogen molecule have in the end of glycogenolysis if only 10,000 glucose residues are left? Define the term “glycogenolysis” and name the key enzyme. Using iodine to test for the presence of starch is a common experiment.
