And that electric repulsion will increase the energy of this molecule compared to the case when these two groups would point along the equatorial position. So, with that in mind, let's compare the alpha D Glucopyronose and the beta D Glucopyronose in their chair confirmations. So, let's begin with the alpha D glucose. So how many carbon atoms? So we have 1234 carbon atoms within no, we have 12345 carbon atoms within this six membrane ring. Five of these carbon atoms contain the large groups that point or, I'm sorry, four of these five carbon atoms contain these large groups that point along the more stable equatorial position.
