Draw the Fischer projection for the D-2-ketotetrose.
Draw the Fischer projection for the D-2-ketotetrose. Switch between an aldose and a ketose by clicking on "switch carbonyl group." Add or delete carbon atoms using the add (" +") or delete ("x") buttons. Clicking on a blue box once adds a hydrogen atom (H). Clicking on a blue box again toggles between H and OH.
