## Abstract Transient electric birefringence measurements on poly(Lβlysine hydrobromide) in methanolβwater mixtures have been carried out at various solvent compositions in the vicinity of the helixβcoil transition region (from 87 to 98 vol % methanol). Anomalous birefringence transients were obser
Poly-L-lysine exists as an a-helix at high pH and a random coil at neutral pH. When the a-helix is heated above 27ΠC, the macromolecule undergoes a conformational transition to a b-sheet. In this study, the stability of the secondary structure of poly-L-lysine in solutions subjected to shear flow, a
