Cholesterol stimulation of phosphatidyl choline formation.
The conversion of ethanolamine to phosphatidyl choline was studied in liver slices from rats exix>sed to a high dietary intake of cholesterol in the presence of cholic acid. Cholesterol stimulated phosphatidyl choline formation per unit weight of liver tissue and increased the total liver muss thereby increasing further the total yield of phosphatidyl choline. These results are contrasted with ...
متن کاملLateral distribution of cholesterol in dioleoylphosphatidylcholine lipid bilayers: cholesterol-phospholipid interactions at high cholesterol limit.
Lateral organization of cholesterol in dioleoyl-phosphatidylcholine (DOPC) lipid bilayers at high cholesterol concentration (>45 mol%) was investigated using steady-state fluorescence anisotropy and fluorescent resonance energy transfer techniques. The recently devised Low Temperature Trap method was used to prepare compositionally uniform cholesterol/DOPC liposomes to avoid the problem of lipi...
متن کاملdetermination of phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl inositol and phosphatidic acid in different varieties of soybean cultivated in iran
introduction: crude vegetable oils contain some quantities of phospholipids. the highest concentration of phospholipids is usually found in crude soybean oil. the presence of phospholipids in the crude and refined oils create undesirable effects on the quality and quantity of the oil during refining operations or use by the consumer. however, if phospholipids are extracted properly from the oil...
متن کاملCholesterol perturbs lipid bilayers nonuniversally.
Cholesterol is well known to modulate the physical properties of biomembranes. Using modern x-ray scattering methods, we have studied the effects of cholesterol on the bending modulus K(C), the thickness D(HH), and the orientational order parameter S(xray) of lipid bilayers. We find that the effects are different for at least three classes of phospholipids characterized by different numbers of ...
متن کاملNon-Gaussian distribution in random advection dynamics.
Simulations of vortex tube dynamics reveal that the non-Gaussian nature of turbulent fluctuation originates in the effect of random advection. A similar non-Gaussian distribution is found numerically in a simplified statistical model of random advection. An analytical solution is obtained in the mean-field case.
