starch is a heteropolymer of amylose and amylopectin or homopolymer of glucose units?

Starch is a homopolymer of glucose. The two types of glucose units present in starch are amylose and amylopectin.

Amylose is made up of D-glucose units while the ​amylopectin is a highly branched polymer of glucose.

Note: Heteroploymer is one that contains sugar acids, amino sugars or noncarbohydrate substances in addition to monosaccharides like glucose.
