What are sterol absorption markers?
What are sterol absorption markers? From serum noncholesterol sterols cholestanol, campesterol, and sitosterol are surrogate markers of cholesterol absorption, but reflect also cholestasis, while those of lathosterol reflect cholesterol synthesis and hepatic parenchymal function. What is a hyper absorber of cholesterol? Hyper-absorbers – poor synthesisers. Plasma PS (campesterol/sitosterol) are markers of the intestinal absorption of cholesterol. Their plasma levels are low because of their elimination through ABCG5/ABCG8 excretion. Cholestanol and lathosterol, precursors of cholesterol, are markers of cholesterol synthesis. How are sterols absorbed? Most humans absorb about 50% of the sterols in the gut, but some people are hyperabsorbers (60-80%)...
