On Membrane Phospholipids and Protein-lipid Association
Membranes of blood cells have an asymmetric bilayer distribution of phospholipid classes. In both erythrocytes and platelet plasma membranes the choline containing phospholipids (sphingomyelin and phosphatidylcholine) are preferentially located in the outer half of the membrane, whereas a large fraction of phosphatidylethanolamine and nearly all phosphatidylserine are confined to the cytoplasmi...
متن کاملLipid peroxidation in cell membrane phospholipids
duced by reactive oxygen species and/or free radicals leads to alterations in the membrane structure and functions of cells, and has been proposed as a major mechanism for the onset of several pathological events in vivo, including postischemicreperfusion injury, cancer, senile dementia and aging. A number of studies have shown that peroxidation of membrane lipids in cells gives rise to highly ...
متن کاملSpectral Imaging to Measure Heterogeneity in Membrane Lipid Packing
Physicochemical properties of the plasma membrane have been shown to play an important role in cellular functionality. Among those properties, the molecular order of the lipids, or the lipid packing, is of high importance. Changes in lipid packing are believed to compartmentalize cellular signaling by initiating coalescence and conformational changes of proteins. A common way to infer membrane ...
متن کاملBinding of peripheral proteins to mixed lipid membranes: effect of lipid demixing upon binding.
Binding isotherms have been determined for the association of horse heart cytochrome c with dioleoyl phosphatidylglycerol (DOPG)/dioleoyl phosphatidylcholine (DOPC) bilayer membranes over a range of lipid compositions and ionic strengths. In the absence of protein, the DOPG and DOPC lipids mix nearly ideally. The binding isotherms have been analyzed using double layer theory to account for the ...
متن کاملLateral diffusion of phospholipids in the plasma membrane of soybean protoplasts: Evidence for membrane lipid domains.
Fluorescent lipid and phospholipid probes were incorporated at 4 degrees C into soybean protoplasts prepared from cultured soybean (SB-1) cells. Fluorescence microscopy showed that the plasma membrane as well as the nucleus were labeled. Fluorescence redistribution after photobleaching (FRAP) analysis was performed on these cells at 18 degrees C to monitor the lateral mobility of the incorporat...
