I am confused as to where the beta is coming from (in the alpha-1,2-beta glycosidic bond in sucrose). I understand that the alpha is from the anomeric carbon of the glucose, but I don't see how the beta is part of this
To me it seems as though the hydroxyl on the anomeric carbon of fructose (i.e. th OH below the plane of C-2 in fructose) causes it to be an alpha form, correct? If so, then why is it called a beta linkage?
