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. But along the carbon number one, this hydroxyl group points along the axial position, which is, as we said just a moment ago, the higher in energy position. And if we examine the beta case, we'll see that the stereo chemistry and carbon number one of the beta anomer is the opposite. And this hydroxyl group actually points along the equatorial position.
