WebRuies for Fischer Projection A Fischer projection is used to differentiate between L- and D- molecules. On a Fischer projection, the penultimate carbon of D sugars are depicted with hydrogen on the left and hydroxyl on the right. L sugars will be shown with the hydrogen on the right and the hydroxyl on the left. CHO CH20H CHO CH20H D-Glyceraldehyde WebQuestion: 1.)
