Sluggish sitosterol turnover and hepatic failure to excrete sitosterol into bile cause expansion of body pool of sitosterol in patients with sitosterolemia and xanthomatosis.
Sitosterolemia and xanthomatosis are characterized by the development of tendon and tuberous xanthomas at an early age and premature atherosclerosis despite normal plasma cholesterol concentrations. The reason(s) for the xanthoma formation and premature atherosclerosis are not clearly understood.

متن کاملDiscrimination between cholesterol and sitosterol for absorption in rats.
The intestinal absorption of cholesterol and sitosterol was compared in rats. The intragastric administration of a single emulsified lipid meal containing either 50 mg of [4-14C]cholesterol or [4-14C]sitosterol resulted in the lymphatic absorption of 18.2% and 0.42% of each sterol, respectively, in 6 hr. This difference was unaltered when the mucosal sterol load was equalized by reducing the ch...

متن کاملEffect of Dihydrocholesterol and ^-Sitosterol on Cholesterol Atherosclerosis in Rabbits
While dihydrocholesterol lowered total plasma cholesterol in the rabbit, it did not promote the regression of either the aorta lipid fractions or plaque areas in atherosclerotic animals. A comparative study of the toxicities of /3-sitosterol and dihydrocholesterol disclosed that dihydrocholesterol, fed for a 7 month period, resulted in aorta plaque formation and caused the development of liver ...
