Photolabelling of membrane proteins with photoactive phospholipids.
Photoactive probes have been introduced recently to study the hydrophobic sector of integral membrane proteins. A simple procedure to synthesize a new series of highly radioactive aryl azido-phospholipids is presented. They effectively exchange with the boundary lipids and, on illumination, the cross-link to several membrane proteins with high efficiency. The procedure and analysis of labelling...
متن کاملMembrane phospholipids of the ocular tunica fibrosa.
The authors compared porcine corneal and scleral membrane phospholipids determined with use of 31P nuclear magnetic resonance (NMR). These tissues make up the tunica fibrosa (outer coat) of the eye. Since the sclera, unlike the cornea, does not possess an epithelium or an endothelium, comparative analysis of these tissues included examination of the cornea with and without its epithelium and en...
متن کاملOn 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 کاملIncorporation of docosahexaenoic acid into nerve membrane phospholipids: bridging the gap between animals and cultured cells.
BACKGROUND Functional maturation of nervous tissues depends on membrane accretion of docosahexaenoic acid (DHA). Animal studies have shown that incorporation of dietary DHA into membrane phospholipids is dose dependent. The molecular effects of DHA are commonly studied in cultured cells, but questions remain about the physiologic connection between animal and cell models. OBJECTIVE We develop...
