In this paper two points are considered: the methods of evaluating the helical content 8 and the calculation of the parameters of the transition from experimental data and its interpretation. The parameter AH obtained is in good agreement with the calorimetric one and v is found to be independent of
## Abstract The thermal helix–coil transition of poly(γ‐benzyl L‐glutamate‐__co__‐ε‐carbobenzoxy‐L‐lysine) copolypeptides was studied in solvent mixtures of different compositions. The cooperativity parameter __v__ changes linearly with polymer (and solvent) composition, whereas the heat of the tra
## Abstract The heal of solution of Poly‐ε‐carbobenzoxy‐L‐lysine and of a series of its copolymers with phenylalanine was measured as a function of solvent composition. The enthalpy change of the helix‐to‐coil transition was estimated for the various cases. The previous findings that side chains do
