## Abstract The conformational transition of polyβLβtyrosine in 0.1__M__ KCl was investigated by ORD and infrared spectroscopy, potentiometric titration, and sedimentation velocity experiments. It is shown that the fully ordered conformer is obtained by slow titration of the random coil with 0.1__N

## Abstract Absorption, circular dichroism (CD), and optical rotatory dispersion (ORD) measurements were carried out on polyβLβtyrosine in trimethyl phosphate solution over the spectral range 185β600 mΞΌ. There is evidence in the CD spectrum for side chainβside chain interactions in polyβLβtyrosine.
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
