On Carbon # 1, I assumed that the -OH group should always point up. I assumed it must always be UP because, from doing practice problems, OH group, on glucose, alternates between up and down on each carbon.
However, I have just come across a problem in which we are given cyclic glucose with the -OH group on C1 pointing down.
After doing a bit of thinking, I believe that it can be up or down because the C6 hydroxyl (in the straight chain form) can attack the carbonly of C1 from either side.
Am I right??
