The glycosidic bond in a disaccharide was determined to be α (1→6) . Hydrolysis of the disaccharide produced one galactose and one fructose. Draw the structure of the disaccharide.
The shell of a shrimp is composed of chitin. If you eat a boiled shrimp without removing the shell, will your body break the shell down into its component sugars? Explain. (Hint: Compare chitin’s structure to that of amylose and cellulose.)
Glycogen and amylopectin are both branched polymers of glucose. Read the descriptions of each in Section 6.6. Which molecule has a more compact structure? Explain.
On an exam, a student was asked to draw the Fischer projection of l-glucose, but he had only memorized the structure of d-glucose. He wrote the structure of d-glucose and switched the hydroxyl group on C5 from the right to the left. Was his answer correct? If not, what is the name of the aldose that he drew?
