Five- and six-membered ring structures are common in carbohydrates and are often in equilibrium with each other. The five-membered ring structures are called furanose forms; the six-membered ring structures are pyranose forms. d-Ribose, especially in its ?-furanose form, is a familiar carbohydrate.
