Oxygen is known to partition with an increasing concentration gradient toward the hydrophobic membrane interior. At partial pressures (P-O2) of 100 Atm or more, this concentration gradient is sufficient to induce paramagnetic effects that depend…
The interaction of chloroform with bilayers of dimyristoylphosphatidylcholine (DMPC) has been studied by deuterium and phosphorus-31 nuclear magnetic resonance (NMR). Orientational order has been measured as a function of temperature at many sites in…
The pulsed field gradient NMR method for measuring self-diffusion has been used for a direct determination of the lateral diffusion coefficient of cholesterol, fluorine labeled at the 6-position, for an oriented lamellar liquid-crystalline phase of…
H-2 nuclear magnetic resonance (NMR) spectra were obtained at 30.87 MHz for 8% (w/v) aqueous dispersions of mixtures of bile salts (MBS), mixed intestinal lipids (MIL; myristic acid, monomyristoylglycerol dimyristoylphos-phatidylcholine = 5:1:1), and…
