| Outline of Final Research Achievements |
Analysis of the relationship between the molecular structure and hydration of amino acids in water was carried out with the aim of clarifying the solvent-solute interaction, as represented by the parameter α, and inhibition of enzyme activity. The hydration of Gly-Gly, which is a dimer of glycine, in water increased to a greater extent than expected. Further, hydration of the Gly-trimer increased to a greater degree than that of the Gly-dimer, but the rate of increase was variable. Thus, the hydration of these Gly-oligomers is not simply the sum of the hydration of their constituent Gly residues. Furthermore, the differences in hydration of several D- or L-type hydrophobic amino acids may be not due to differences in their stereostructure. The solvent-solute interaction, represented by the parameter α, does not inhibit the enzyme responsible for browning of apples, due to its limited contribution.
