(a) Interpretation: The more stable chair form of fucose is to be drawn. Concept introduction: In Fischer projection formula, the horizontal and vertical line represents the bonds that are present above and below the plane, respectively. The verticals bonds are represented as dashed wedge and horizontal bonds as dark wedge. The substituents present “up” and “down” in Haworth projection are represented as up and down bonds in chair conformation.

Replace the appropriate hydrogens with the appropriate -CH3 or other groups. 3. If you need to start over, Undo or choose a Newman projection from the Templates toolbar (bottom). Important: Never delete the hydrogen atoms or bonds directly attached to the template, and do not move them by dragging or dropping them. That will break the projections structures. Only replace them! ▸ View Available Hint(s) 0 2 H± 3D EXP. L ד י CONT. 2 H 0 N о
