| Common Name | (22alpha)-hydroxy-sitosterol |
|---|
| Description | (22alpha)-hydroxy-sitosterol 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 (22alpha)-hydroxy-sitosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). (22alpha)-hydroxy-sitosterol can be found in a number of food items such as cottonseed, oil-seed camellia, cloves, and dill, which makes (22alpha)-hydroxy-sitosterol a potential biomarker for the consumption of these food products. |
