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

## Abstract The electric birefringence of poly‐L‐lysine hydrobromide in methanol–water mixtures has been measured at 25 °C over a wide range of field strengths by use of the rectangular pulse technique. An abrupt change in the specific Kerr constant was observed between 87 and 90 vol % methanol, co

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

## Abstract Poly(L‐lysine) of various molecular weights between 2700 and 475,000 was spin‐labeled. From the electron spin resonance spectra, the degree of freedom of the nitroxide was determined by calculation of the rotational correlation time as the poly(L‐lysine) underwent the pH‐induced random
