HELIX-COIL TRANSITION IN POLY(GAMMA-BENZYL-L-GLUTAMATE) AND POLY-EPSILON-CARBOBENZOXY-L-LYSINE

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 ΔH 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. Copyright © 1969 John Wiley & Sons, Inc.
