Fig. 2 in On the free radical scavenging and metallic ion chelating activities of pyridoxal - Could the pro-oxidant risk be competitive?

Fig. 2. Optimized structures of transition states (TSs) of FHT reactions of neutral pyridoxal with HOO● and NO ● at C9H, and with HO● at C6H to C9H and O12H 2 calculated in water. Optimized structure of FHT with HO● at O10H obtained in the gas phase. Distances are in angstrom (Å) and angles are in degree (o).
