Another good thing about starch: Each little glucose likes to have water all around it. That can be really hard on the plant. In a starch polymer, the glucose units have other glucose units around them, and that works just as well as water. So, the plant doesn't need so much water, and everybody's happy! We need glucose for energy, too. You even need energy to think! When you eat starchy food, special proteins called enzymes which are also polymers, by the way break starch down into glucose, so your body can burn it for energy.
This starts happening right in your mouth! There's an enzyme in your spit yep, your spit! Check out this link to see how you can taste this enzyme working.
