Weborientation (the far right formula). When writing Fischer projection formulas it is important to remember these conventions. Since the vertical bonds extend away from the viewer and the horizontal bonds toward the viewer, a Fischer structure may only be turned by 180º within the plane, thus maintaining this relationship. WebFischer projections are just another way of drawing compounds contacting chirality centers. They were initially proposed by Emil Fischer for making it easier to draw the structures of compounds containing multiple chirality …
Web2. Manipulate the Fischer projection so this hydroxyl group is on the bottom. 3. Draw the Haworth projection so that the ring oxygen is on the top. For pyranoses, draw the six-membered ring laying on it side with a oxygen at the upper right. 4. Substituents on the right side of the Fischer projection will be on the bottom face of the Haworth ...
