Figure 4. Contributions of particular atoms to the gerosuppressant activities of OA and DOA. Figures provides a detailed comparison of the atomic groups that are likely to be responsible for the differences (blue circles) in the predictions of antioxidant, anti-inflammatory, antineoplastic, and apoptosis agonist activities with a Pa > 0.4 obtained for the hemiacetalic closed forms of OA and DOA that are not predicted (Pa < 0.2) for the dialdehydic open forms of OA and DOA.
