Solubility Limits of Cholesterol, Lanosterol, Ergosterol, Stigmasterol, and β-Sitosterol in Electroformed Lipid Vesicles.
Here we use nuclear magnetic resonance to measure the solubility limit of several biologically relevant sterols in electroformed giant unilamellar vesicle membranes containing phosphatidylcholine (PC) lipids in ratios of 1:1:X DOPC:DPPC:sterol. We find solubility limits of cholesterol, lanosterol, ergosterol, stigmasterol, and β-sitosterol to be 65-70%, ~35%, 30-35%, 20-25%, and ~40%, respectiv...
متن کاملCholesterol, -Sitosterol, Ergosterol, and Coprostanol in Agricultural Soils
represent a minor source of cholesterol (Ibanez et al., 2000). In this work we analyzed the sterol content of agricultural soils. Ergosterol is the main endogenous sterol of fungi and Three eukaryotic sterols, cholesterol, -sitosterol, and ergosterol were of some microalgae. Ergosterol content in fungal cells chosen as representative of the animal, plant, and fungal kingdoms, varies in differen...
متن کاملSurface modification of polymeric vesicles via host-guest inclusion complexation.
We have prepared a novel kind of building block (CD-PI-CD) of polyether imide (PI) with beta-cyclodextrin (beta-CD) at the both ends that self-assembles into vesicles in water. The vesicles are "reactive" in supramolecular chemistry because the host groups of beta-CD equally distribute on the inside and outside surfaces of the vesicles. Isothermal titration calorimetry (ITC) and static light sc...
متن کاملThe Influence of Exogenous Steroids on the Growth of Aspergillus niger and Torula utilis
The yield of Aspergillus niger mycelium from a synthetic medium can be increased by the addition of microgram quantities of cholesterol, ergosterol, cholestanol, 7-dehydrocholesterol, stigmasterol, sitosterol, pregnenolone, and the vitamins D. The stimulation is not due to degradation to the acetate level. It is obtained only in highly aerated cultures. The rate of growth of Torula utilis was n...
متن کاملFate of ergosterol and cholestanol in pleuro-pneumonia-like organisms.
Smith, Paul F. (University of South Dakota, Vermillion). Fate of ergosterol and cholestanol in pleuropneumonia-like organisms. J. Bacteriol. 84:534-538. 1962.-Cholesterol, an essential growth requirement of certain pleuropneumonia-like organisms, can be replaced by ergosterol or cholestanol. Since cholesterol is incorporated unchanged, determination was made of the fate of substituted sterols. ...
