The folding of randomly coiled poly(bg1utamic acid) to the helical state has been studied in N-methylacetamide by titration methods. Since this solvent would be expected to form amide-peptide group hydrogen bonds with the unfolded form of the polymer, to a first approximation no helix stabilization

## Abstract There have been many reports that the nuclear magnetic resonance (nmr) spectra of a large number of polypeptides exhibit peak doubling of the α‐carbon and the α‐carbon proton in the helix–coil transition region. One apparent exception to this generalization has been polypeptides with io

## Abstract A polarimetric electric‐field‐jump relaxation apparatus is described and used to determine the relaxation spectrum for the helix–coil transition of poly(α,L‐glutamic acid) in water at 24°C. A maximum relaxation time of 1.7 μc occurs at the transition midpoint (pH = 5.9) yielding a rate
