Electrical characteristics of sphingomyelin bilayer membranes.
Current-voltage characteristics and the conductivity temperature dependence of sphingomyelin bilayer membranes have been determined. The resistances were of the order of 10(8) Omega-cm(2) and exhibited ohmic behavior up to approximately 25 mv followed by increasing conductivity with applied voltage. The current is found to be proportional to a hyperbolic sine function of the voltage. The temper...
متن کاملMolecular-scale structural and functional characterization of sparsely tethered bilayer lipid membranes.
Surface-tethered biomimetic bilayer membranes (tethered bilayer lipid membranes (tBLMs)) were formed on gold surfaces from phospholipids and a synthetic 1-thiahexa(ethylene oxide) lipid, WC14. They were characterized using electrochemical impedance spectroscopy, neutron reflection (NR), and Fourier-transform infrared reflection-absorption spectroscopy (FT-IRRAS) to obtain functional and structu...
متن کاملThermodynamic characterization of bilayer- nonbilayer phase transitions of phospholipid membranes
We determined thermodynamic properties of phase transitions between bilayer and nonbilayer for phosphatidylcholines with saturated hydrophobic chains (C18:0-PC, O-C18:0PC) and phosphatidylethanolamines with unsaturated ones (C18:1(cis)-PE, C18:1(trans)-PE) by means of calorimetry under ambient pressure and optical measurements under high pressure. The thermodynamic quantities of the transitions...
متن کاملRhodopsin in bilayer membranes.
Visual excitation is initiated with the absorption of light by the membrane-bound visual pigment rhodopsin. The effect of light on rhodopsin is now quite generally believed to be a photoisomerization of the chromophore, retinaldehyde, from the 1 1-cis to the all-rransconliguration(Hubbard & Kropf, 1957; Wald, 1968). This is followed by changes in the shape of the protein, and these lead to cond...
