And this Fructose molecule is known as Fructopyrenose. So Fructose a furnace simply means five membrane ring, and Pyrenose is in this case, means six membrane. And just like we have the alpha and the beta animals, we can also form the alpha and the beta anomers of Fructopyranos. So basically, the takeaway point from this lesson is the fact that inside our body, the open chain form of sugars does not actually predominate. It's the ring structure, the ring form that predominates because it's the ring form that is lower in energy and thermodynamically more stable than that open chain form. Now, what I haven't mentioned also is the fact that ribose sugar molecules, which are actually examples of pentosis, so hexoses contain six sugars, but pentosis, like ribose contain five sugars.
