Abstract

The coil to helix conformational transitions undergone by poly‐γ‐benzyl‐~L~‐glutamate in solutions of haloacetic acids and various cosolvents were studied by means of proton magnetic resonance. The results indicate a very small solvent dependence of the α‐CH Helix–coil chemical shift difference. The helical stabilities of PBLG in different solvent mixtures were interpreted in terms of modifications of the “solvent structure.”

## Abstract The helix–coil transition in poly(γ‐benzyl L‐glutamate‐__co__‐γ‐methyl L‐glutamate) copolypeptides was studied experimentally in nonaqueous solvents and the results compared with theory. It is found that the transition can be described by the same theory as for the homopolypeptides, but

## Abstract The thermal helix–coil transition of four samples of poly(γ‐benzyl‐L‐glutamate) in the dioxane–dichloroacetic acid (DCA) mixture was studied by optical rotatory dispersion method. The transition occurred at very high DCA content (97.5% by weight) in this system. The transition parameter

The effects of deuteration and of changes in solvent composition on the thermodynamics of the helix-coil transition have been studied by calorimetric and optical measurements in the poly-7-benzyl-Lglutamatedichloroacetic acid-l,%dichloroethane system. For a given solvent composition, deuteration of
