The effects of cholesterol and cholesterol-derived oxysterols (cholestanone, cholestenone, coprostanone and epicoprostanol) on adipocyte ghost membrane fluidity were studied using a fluorescence depolarization method. The fluorescence anisotropy of the treated membranes was determined using 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1-(4-trimethylammoniumphenyl)-6-phenyl-1,3,5-hexatriene (TMA-DPH). Cholestanone

Modification of steroid molecules by introducing heterocyclic ring into the core structure of steroids has been utilized as an attractive approach for either cancer prognosis or diagnosis. Several new cholestanoheterocyclic steroids were synthesized, and analytical and spectral data proved the

We investigated the effects of pectin with different degrees of methylation (34.5, 70.8, and 92.6%, respectively) on the composition and concentration of intestinal and fecal bile acids and neutral sterols in conventional and germfree rats. Diets containing 6.5% pectin (galacturonan)

After oral administration of a mixture of [1,2(n)-3H]cholesterol and [4-14C]cholesterol to a baboon, fecal coprostanone had a 46% lower 3H/14C ratio than the dose administered. Loss of 3H by enolization of the 3-ketone could account for the decrease in 3H/14C.
