    For some reason i keep finding mixed answers for this. Does anomeric carbon of beta-D-Fructose point up or down? I think its up but in structure of sucrose, it points down and still is beta. Im confused.

      The -OH group on the anomeric carbon of beta-D-Fructose points up. If it points up, its beta. If it points down, then its alpha.
