LIPID HEADGROUP HYDRATION STUDIED BY H-2-NMR - A LINK BETWEEN SPECTROSCOPY AND THERMODYNAMICS

Abstract:

The conformational and dynamic response of the phosphatidylcholine headgroup to hydration has been characterized by 2H-NMR measurements of selectively deuterated DOPC at positions α, β, and γ, and to complement the structural results from diffraction studies. Quadrupole splittings (ΔνQ) and spin-lattice relaxation rates (1/T1) were monitored over the range of water/lipid mole ratios from 4 to 100. Their hydration dependence reveals a concerted change in headgroup conformation together with an...
