There are two components which make up starch, amylose and amylopectin. Amylose, the unbranched form, has alpha 1,4 linkages between glucose molecules. It is a compact molecule, and soluble in water, making it ideal for storage in plant cells. It is broken down by the enzyme alpha amylase for energy.
