Why does amylase break down starch into sugar?

Starch is a complex carbohydrate or polysaccharide, which consists of many monosaccharide molecules (glucose) joined together.Since the cell in the body has partially permeable membrane, it cannot absorb big size molecules, such as starch and protein.Hence, starch needs to be broken down to glucose before it can be absorbed into the cells of the body.
