Starch contains two polymers of glucose, they are amylose and amylopectin. Amylose differs from amylopectin in that

Amylose is a straight chain whereas amylopectin is a branched chain polymer.

Explanation:

Amylose differs from amylopectin because amylose is a straight chain while on the other hand, amylopectin is a branched chain polymer. Branched chain polymers refers to main chain with smaller chains as branches of main chain while straight chain polymer has only main chain and no branches of main chain. Starch comprise of about 10-20% amylose and 80-90% amylopectin. Starch is considered as the main storage of energy for green plants.
