Helix–coil transition in poly(γ‐benzyl‐<scp>L</scp>‐glutamate) and poly‐ε‐carbobenzoxy‐<scp>L</scp>‐lysine

Abstract

Abstract In this paper two points are considered: the methods of evaluating the helical content θ and the calculation of the parameters of the transition from experimental data and its interpretation. The parameter Δ H obtained is in good agreement with the calorimetric one and v is found to be independent of temperature and solvent and in agreement with the ordinarily accepted value for poly(γ‐benzyl‐ L ‐glutamate). The different methods of estimating θ are discussed for both polypeptides.
