Answer to Problem 18.149EP
The type of glycosidic linkage present in amylopectin and glycogen is same, that is both have
Explanation of Solution
Amylopectin is a branched polysaccharide of starch. Only one type of monosaccharide, glucose is present in amylopectin. The glycosidic linkages present in amylopectin are
Glycogen is a branched glucose polysaccharide. In humans and animals, it stores glucose. When excess of glucose is present in the human body, it is stored as glycogen. In glycogen, both
Hence, the type of glycosidic linkage present in amylopectin and glycogen is same, that is both have

Answer to Problem 18.149EP
The degree of branching is more in glycogen than amylopectin.
Explanation of Solution
Amylopectin is a branched polysaccharide of starch. Only one type of monosaccharide, glucose is present in amylopectin. The glycosidic linkages present in amylopectin are
Glycogen is a branched glucose polysaccharide. In humans and animals, it stores glucose. When excess of glucose is present in the human body, it is stored as glycogen. In glycogen, both
The difference between amylopectin and glycogen is based on the presence of glucose units in between the branches and the total number of glucose units present in the carbohydrate. There is about three times more branching in glycogen than amylopectin. There are about 1000,000 units of glucose present in glycogen while in amylopectin 10,000 units of glucose are present.
Hence, the degree of branching is more in glycogen than amylopectin.
