Why is starches another name for complex carbohydrates?

Carbohydrates are one of the four macromolecules of life- Lipids, Proteins, Nucleic Acids, and Carbohydrates. These molecules have simple forms called monomers and more complex forms called polymers. Starches are a polymer of carbohydrates or a complex form of carbohydrates. A monomer of carbohydrates is a monosaccharide or simple sugar. To make a polymer there needs to be more than one monomer together. An example is the monomer glucose. When you have two glucose molecules bonded together you get the polymer maltose. Monomers glucose and fructose bonded together makes polymer sucrose. These examples are disacchrides. Di- meaning two sacchrides- meaning sugar. Polysacchrides Poly- meaning many and sacchrides- meaning sugar. Starch is a polysacchride, so it has many monomers bonded together. Therefore a complex carbohydrate or a polymer of a carbohydrate.
