Difference between Amylose and Amylopectin

Medium Biochemistry Carbohydrates

Carbohydrates are essential biomolecules that serve various functions in living organisms. They can exist in several structural forms, such as monosaccharides, oligosaccharides, and polysaccharides. One well-known carbohydrate is starch, which is utilized as an energy storage molecule in plants. Starch is composed of two types of molecules: amylose and amylopectin. Considering the structure and function of carbohydrates, which of the following statements accurately describes a key difference between amylose and amylopectin?

Amylose is a linear polymer, while amylopectin is a branched polymer.

Amylose is less soluble in water than amylopectin.

Amylose is composed primarily of 1,6-glycosidic linkages, while amylopectin uses 1,4-glycosidic linkages.

Amylose contains more glucose units than amylopectin.
