Solubilization of acyl heterogeneous triacylglycerol in phosphatidylcholine vesicles.
The amount of acyl heterogeneous triacylglycerol (TG(HET)) solubilized by phosphatidylcholine (PC) vesicles, prepared by co-sonication of egg PC and small amounts (<6% w/w) of TG(HET), was determined using (13)C nuclear magnetic resonance (NMR). The acyl chains of TG(HET) were predominantly 16 or 18 carbons in length, 50% saturated, and approximately 21.7% (13)C isotopically enriched at the car...
متن کاملSolubilization of triolein and cholesteryl oleate in egg phosphatidylcholine vesicles.
The incorporation of cholesteryl oleate and triolein into phospholipid vesicles was studied in cosonicated mixtures of 94 weight % egg phosphatidylcholine and 6 weight % neutral lipid (0-6% triolein and 6-0% cholesteryl oleate). 13C NMR spectroscopy was used to quantitate both neutral lipids in vesicles containing 90% isotopically substituted [carbonyl-13C]cholesteryl oleate and [carbonyl-13C]t...
متن کاملStudies on Phosphatidylcholine Vesicles
The partial specific volume of phospholipid vesicles was determined by the sedimentation velocity method in various concentrations of hydrogen and deuterium oxide mixture. Since the density of D20 is very much greater than the reciprocal of the specific volume of phospholipids, the density of DzO-Hz0 medium corresponding to zero redistribution of phospholipids during sedimentation can be obtain...
متن کاملPhysical properties of phosphatidylcholine vesicles containing small amount of sodium cholate and consideration on the initial stage of vesicle solubilization.
The effects of sub-solubilizing concentrations of sodium cholate (Na-chol) on several physicochemical properties of phosphatidylcholine (PC) small unilamellar vesicles (SUV) were considered in connection with the initial stage of membrane solubilization. ESR spectra of 12-doxylstearic acid (12-DS) in phosphatidylcholine from egg yolk (EPC) or dimyristoylphosphatidylcholine (DMPC) SUV at low con...
متن کاملpH-dependent domain formation in phosphatidylinositol polyphosphate/phosphatidylcholine mixed vesicles.
Phosphatidylinositol polyphosphates (PI-PPs) have been shown to mediate a large variety of physiological processes by attracting proteins to specific cellular sites. Such site-specific signaling requires local accumulation of PI-PPs, and in light of the rich headgroup functionality, it is conceivable that hydrogen bond formation between adjacent headgroups is a contributing factor to the format...
