Explanation:
Detailed explanation-1: -Glycogen: This polysaccharide is the polysaccharide found in animals to store energy and is composed of alpha-1, 4-glycosidic bonds with branched alpha-1, 6 bonds present at about every tenth monomer.
Detailed explanation-2: -Polysaccharides are very large polymers composed of tens to thousands of monosaccharides joined together by glycosidic linkages. The three most abundant polysaccharides are starch, glycogen, and cellulose.
Detailed explanation-3: -Starch is a storage form of energy in plants. It contains two polymers composed of glucose units: amylose (linear) and amylopectin (branched). Glycogen is a storage form of energy in animals. It is a branched polymer composed of glucose units.
