Starch is made up of amylose and amylopectin, which are similar in structure. What is the difference between amylose and amylopectin?

• A. Amylose is composed of glucose units connected by α-1,4 glycosidic linkages, while amylopectin is composed primarily of glucose units connected by α-1,4 glycosidic linkages with branching points formed by α-1,6 glycosidic linkages.
• B. Amylose is composed primarily of glucose units connected by α-1,4 glycosidic linkages with branching points formed by α-1,6 glycosidic linkages, while amylopectin is composed of glucose units connected by α-1,4 glycosidic linkages.
• C. Amylose is composed of glucose units connected by α-1,6 glycosidic linkages, while amylopectin is composed of glucose units connected by α-1,4 glycosidic linkages.
• D. Amylose is composed of glucose units connected by α-1,4 glycosidic linkages, while amylopectin is composed of glucose units connected by α-1,6 glycosidic linkages.
