And the alpha case, it points in the opposite direction of this group here. So these two products are animals. We have the alpha and the beta anomer and they're called glycosides. Now, this bond shown red the bond between the animary carbon number one on that glucose molecule and this oxygen that is part of this methanol is known as the Oglycocitic bond. We call it the Oglycocitic bonds. That basically differentiate from the anglyacitic bond that we'll talk about in just a moment.
