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

Cholesterol-derived oxysterols such as cholestanol, cholestanone and coprostanone were able to potentiate epinephrine-induced lipolysis in intact rat adipocytes but not cholesterol. The relative potency of the oxysterols followed the sequence: cholestanone > or = coprostanone > cholestanol. Cholestanone was selected

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.

Young adult rats were fed ad libitum for 4 wk on defined diets containing either no fiber, 10% levels of insoluble fiber sources [cellulose, wheat bran, alfalfa, mixed fibers (Fibyrax)], 5% levels of soluble fiber sources [pectin, guar gum, psyllium

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)
