Figure 8.

Haworth projection for sucrose alias α-d-glucopyranosyl-(1→2)-β-d-fructofuranoside. The figure also shows the labeling of some specific atomic sites; all labels (shown and not shown in the figure) are described as in the following paragraph. All carbon atoms (not shown) are labeled C and a clockwise (glucose) or anticlockwise (fructose) sequential number (C₁ on glucose and C₂ on fructose are marked as a reference); hydroxyl oxygen atoms are numbered like the nearest carbon (i.e., O2g is attached to C₂ on the glucose side). The bridge oxygen is Ob, and the ring oxygens are Org and Orf for glucose and fructose rings, respectively. All other hydroxyl hydrogens are labeled H, while the carbonyl hydrogens (not shown) are labeled M.
