Thermodynamics of association

Among other approaches, a theory for intermolecular interactions in dilute block copolymer solutions was presented by Kimura and Kurata (1981). They considered the association of diblock and triblock copolymers in solvents of varying quality. The second and third virial coefficients were determined using a mean field potential based on the segmental distribution function for a polymer chain in solution. A model for micellization of block copolymers in solution, based on the thermodynamics of associating multicomponent mixtures, was presented by Gao and Eisenberg (1993). The polydispersity of the block copolymer and its influence on micellization was a particular focus of this work. For block copolymers below the cmc, a collapsed spherical conformation was assumed. Interactions of the collapsed spheres were then described by the Hamaker equation, with an interaction energy proportional to the radius of the spheres.

There has been much interest in recent years in the quantitative determination of the energy aspects of hydrogen bonds by spectroscopic methods (Pimentel and McClellan, 1960). Much information is available in the literature on the thermodynamics of association due to hydrogen bonding involving O—H bonds. The...

Just as chemical exchange can broaden proton NMR spectra (Section 13.5), electron exchange between two radicals can broaden EPR spectra, therefore the distance between two spin probe molecules maybe measured from the line widths of their EPR spectra. The effect can be used in a number of biochemical studies. For example, the kinetics of association of two polypeptides labeled with the synthetic amino acid 2,2,6,6,-tetramethylpiperidine-l-oxyl-4-amino-4-carboxylic acid (6) can be studied by measuring the line width of the EPR spectrum of the label as a function of time. Alternatively, the thermodynamics of association may be studied by examining the temperature dependence of the EPR line width.

A detailed investigation on the thermal denaturation of such a protein and of the thermodynamics of association of S -protein with -peptide and with synthetic S-peptide analogs seemed therefore particularly interesting. We decided to study the thermal denaturation of intact RNase-A by means of differential scanning calorimetry, which as far as I know, we were the first to apply to the study of concentrated biopolymers solutions [16] using a commercially available apparatus, and then to study with the LKB microcalorimeter the enthalpy of recombination of -protein with 5-peptide as well as with S-peptide analogs [7]...
