## Abstract Random copolymers of L‐glutamic acid and ortho‐nitrobenzyl‐L‐glutamate were synthesized with different percentages of nitrobenzyl‐L‐glutamate, from 3 to 22%. These copolymers were studied by circular dichroism (CD) and potentiometric titrations in aqueous solutions in order to determine

## Abstract The potentiometric titration of random copolymers of L‐lysine and L‐alanine containing 0–35% alanine was carried out. The standard free‐energy change for the transition of coil to helix was calculated from the titration curve, and was treated by taking account of first‐neighbor interact

## Abstract Pinacyanol in the presence of an excess of poly(L‐glutamic acid) [polymer/dye ratio (__P__/__D__) > 10] exhibits different absorption spectra in the visible region when bound to the slightly charged polypeptide in the α‐helical conformation or to the nearly completely dissociated polype
