Ques: Answer the following question given this paragraph: Note the Pattern Because carbohydrates have a carbonyl functional group and several hydroxyl groups, they can undergo a variety of reactions. Two familiar polysaccharides are starch and cellulose, which both hydrolyze to produce thousands of glucose units. They differ only in the connection between glucose units and the amount of branching in the molecule (Figure 24.22 "The Polysaccharides Starch and Cellulose"). Starches can be coiled or branched and are hydrolyzed by the enzymes in our saliva and pancreatic juices. Animal starch, called glycogen, is stored in the liver and muscles. It consists of branched glucose units linked by bonds Saylor URL: http://www. saylor. org/books. Q: Animal starch, called glycogen, is stored in the liver and where else?
