Answer 1

Correct choice is (a) Starch from maize contains 15-30% amylopectin and 85-70% amylose

Best explanation: It is a high polymer carbohydrate, starch produced from maize kernels contain 15-30% amylose and 85-70% amylopectin. It is hydrolyzed by acids, alkalis, and enzymes. Starch can form gel on reaction with water under suitable conditions.
