Notes:
A model has been developed for approximating the free energy of collagen fibril formation (ΔFf) and the equilibrium solubility of collagen under physiological conditions. The model utilizes an expression of Flory for rodlike polymers, with the modification that the “pure” anisotropic phase is defined as a collagen fibril containing about 0.3 g water/g collagen. The model also assumes that χ1, the polymer-solvent interaction term, is entirely due to hydrophobic effects. χ1 is estimated from hydrophobic bond energies of amino acid side chains, using the results of Némethy and Scheraga. The temperature dependence of χ1 is utilized to calculate equilibrium solubilities and ΔFf as a function of temperature.
