Explanation:
Detailed explanation-1: -Polysaccharides or carbohydrates are the main source of energy. They are tasteless macromolecules. A polysaccharide is a branched or unbranched polymer of monosaccharides linked by glycosidic bonds. They are insoluble in water and used in storage and structural purposes.
Detailed explanation-2: -As in most oligosaccharides, the monosaccharide units in polysaccharides are joined together in a head-to-tail fashion by glycosidic linkages. Also like oligosaccharides, polysaccharide molecules can be either linear or branched. All polysaccharides, therefore, have one, and only one, reducing end.
