The Stinker Question . To the right is a drawing of a sugar molecule shown in a Fischer projection. In a Fischer projection the atoms (OH and H atoms) to the left and right of the centre vertical line are coming out at you (i.e. a wedge). The groups attached with vertical lines (top and bottom) are bonds projected behind the plane of the page. Draw the Dashed-Wedge line structure and then re-draw the molecule in a zig-zag form with the primary alcohol group on the left and the aldehyde group on the right. CHO OH H H HO OH H OH H CH 2 OH...
