[Denaturation temperature of collagen as a linear function of its amino acid composition].

TD of collagen have been constructed as linear function of fractions of each from 18 amino acids using experimental data for 29 proteins. For coefficient estimation the least squire method have been used. As a result the TD of any collagen may be calculated by using of the function obtained. 14 amino acids strongly influence on TD. The suggestion arises that poly(Gly-Ile-Lys) may produce collagen like structure.
