Monosacharides are the basic unit of carbohydrates. They are the simplest forms of carbohydrates and are usually colorless, water soluable, crystaline solids. Examples of Monosacharides include glucose, fructose, galactose, xylose, and ribose. Monosacharides go together to form disacharides. Honey contains both fructose and glucose. Fructose is a 6-carbon structure and is an isomer of glucose (C6H12O6). Fructose has a cyclic six- membered structure while glucose has a open- chain form with a hydroxyl group on the end.
