Abslract--The variation of the conformation of poly (a L glutamic acid) (PLGA) in water-organic solvent mixtures has been studied as a function of time. These time dependent changes of the conformation have been observed in many water-organic solvent systems. The velocity of this phenomenon is very

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
