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
It is well known that poly(a-cglutamic acid) (PLGA) undergoes a helix to randomcoil transition in aqueous media when the macromolecule is charged by titration with base. This behavior is clearly revealed by studies of optical properties [i.e., ultraviolet absorption and optical rotatory dispersion (
