FIGURE 3 Changes in free amino acid (FAA) and dipeptide (DP) concentrations in AD samples. After LC/MS2 analysis, mole quantities (nmol —dl) of FAAs and DPs in samples from subjects without or with AD were calculated. Then the change in the mean concentration of FAA and DPs in AD (ft = 8) compared to healthy controls (ft = 8) was achieved and expressed as the % change in AD compared to controls ( p <0.05). Modified from Ref (87).

Ozone causes both quantitative and qualitative changes in carbon dioxide fixation patterns. Wilkinson and Bames, using carbon dioxide-found a reduction in radioactivity in soluble sugars and increases in free amino acids and sugar phosphates in white pine after a 10-min exposure to ozone at 0.10 ppm. Miller observed a decrease in carbon dioxide-fixation in ponderosa pines that correlated with loss of chlorophyll, after exposure to ozone at 0.30-0.35 ppm. The Hill reaction rates of chloroplasts isolated from healthy and ozone-injured ponderosa pine indicated that both light and dark reactions of the chloroplasts from ozone-injured plants were depressed. Barnes found depressed photosynthesis and stimulated respiration in seedlings of four pine species of the southeastern United States after exposure to ozone at 0.15 ppm. 

It is not clear yet how large a structural difference between molecules can be simulated. All ligand-receptor simulations so far have involved conservative replacements, although Singh et al. (123) found excellent results with changes in entire amino acid side chains for calculating differences in solvation free energy.
