As we go higher up, the energy increases. And because in this particular case, this hydroxyl group points along the axial position, this molecule will have a higher energy and so will be slightly less stable. And that's exactly why this will predominate over this alpha animal. So, generally speaking, in six member sugar molecules, it's the beta animmer for the glucose that will predominate over the alpha one because of what we just discussed. So the beta anniversary of glucose is favored because all the groups lie along the less hindered equatorial side. Now, we not only have six memory rings in our body, we also have five member rings.
