Principle
Starch is not a single unit, but is composed of amylose and amylopectin. Amylose consists of unbranched chains, while amylopectin is a highly branched mpolysaccharide.Starch has different solubilities in water. One part dissolves in warm water, the other only in hot water. The composition of starch is determined in this experiment.
