351 00 Padova, Ilaly synopsis Circular Dichroism measurements have been carried out on poly-L-lysine (PLL) and on random copolymers of lysine and phenylalanine a t various pH values and in the presence of different amounts of NaClOr. The results indicate that either the homopolymer or the copolymers
## Abstract Random copolymers of Lβglutamic acid and orthoβnitrobenzylβLβglutamate were synthesized with different percentages of nitrobenzylβLβglutamate, from 3 to 22%. These copolymers were studied by circular dichroism (CD) and potentiometric titrations in aqueous solutions in order to determine
Fourier transform ir vibrational circular dichroism (VCD) spectra in the amide I' region of poly(L-lysine) in D,O solutions have confirmed the existence of three distinct conformational states F d an unordered conformational state in this homopolypeptide. Characteristic VCD spectra are presented for
