15N NMR spectroscopy 26 coil-helix transition of poly-L-ornithine

Summary

The coil-helix transition of poly-L-ornithine was studied in water and in a water/methanol mixture (7∶3 by volume) as a function of pH. The 15n NMR chemical shift of N-methylacetamide was measured under analogous conditions and compared with the chemical shifts of poly-L-ornithine to distinguish the influence of the coil-helix transition on the chemical shift from other solvent effects.
