What elements make up a carbohydrate? What ratio are these always found in? Describe a carbohydrate. What is the function of carbohydrates? What is a disaccharide? Draw the reaction of two glucose molecules that combine to form maltose (draw the structures) What are polysaccharides? Describe the structure and function of starch, cellulose, and glycogen. Study the diagrams below, which show carbohydrate molecules. Beside each molecule, write whether it is a monosaccharide, a disaccharide, or a polysaccharide. 1. 2.
