Explain the structure of starch.

Explanation

Starch is a storage polysaccharide in plants. It is a polymer of ` prop`- D- Glucose units and it consists of two components.
(a) Water soluble amylose.
(b) Water insoluble amylopectin.
Amylose is a long linear chain with 200 - 1000 ` prop` - D - Glucose units.
Amylopectin is a branched chain polymer of ` prop ` - D - Glucose units.
