Convert the Fischer projection of D-Altrose to the Haworth projection of the Ě -D-pyranose form. Step 3: To translate the sugar to the Haworth projection, first number the carbon backbone, then number the ring. Then place the substituents. Knowing the sugar is in the D-configuration tells us where to place which substituent? A D-sugar will have the CH2OH group pointing down. the OH group on carbon 1 pointing down. the OH group on carbon 1 pointing up. the CH2OH group pointing up.
