Detailed explanation-1: -Natural starch contains 10–20% amylose and 80–90% amylopectin.
Detailed explanation-2: -Amylopectin is insoluble in water and constitutes about 80-85% of starch. It is a branched-chain polymer of -D-glucose units in which the chain is formed by C1–C4 glycosidic linkage whereas branching occurs by C1–C6 glycosidic linkage.
Detailed explanation-3: -The main sources of starch such as corn, wheat, potato, cassava, and rice contain 70%–80% amylopectin and 20%–30% amylose [32].
