The absorption and circular dichroism spectra of the 1:l copolymer (L-LYS, L-Tyr), have been investigated in aqueous solutions at pH ranging from 3 to 13. The spectral patterns indicate that the fully charged polyampholyte assumes a nonperiodic conformation on the acid and basic sides of the isoelec
