The objective has been to establish if those ions which are known to change the stability of the struct,ure of proteins, have any influence on the properties of ionizable polypeptides. Potentiometric titrations and complementary optical rotation data are presented for aqueous solutions of poly-L-lys
The coil-helix transition has been studied for alkali metal salts of poly (L-glutamic acid) ( P L G ) , i.e., PLGLi, -Na, -K, and -Cs, in aqueous organic solvent systems. Dependence of the transition on the solvent composition has been qualitatively discussed in terms of the solvent dielectric const
