Metabolite Identification
Common NameStigmastanol
DescriptionStigmastanol, also known as sitostanol or (3b)-stigmastan-3-ol, belongs to stigmastanes and derivatives class of compounds. Those are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Stigmastanol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Stigmastanol can be found primarily in blood and feces, as well as in human skeletal muscle tissue. Stigmastanol can be found anywhere throughout the human cell, such as in in the peroxisome, in the cytoplasm, in the Golgi apparatus, and in the membrane (predicted from logP). It can also be found in the extracellular space. Moreover, stigmastanol is found to be associated with sitosterolemia, an inborn error of metabolism. Stigmastanol (sitostanol) is a phytosterol found in a variety of plant sources. Similar to sterol esters and stanol esters, stigmastanol inhibits the absorption of cholesterol from the diet. Animal studies suggest that it also inhibits biosynthesis of cholesterol in the liver (Wikipedia). Stigmastanol is plant stanol. It can decrease the circulating LDL-cholesterol level by reducing intestinal cholesterol absorption (PMID 16910223 ).
