Metabolite Identification
Common Name7a-Hydroxy-cholestene-3-one
Description7a-Hydroxy-cholestene-3-one, also known as cholest-4-en-7alpha-ol-3-one or 7 alpha-3ox-C, belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 7a-hydroxy-cholestene-3-one is considered to be a bile acid lipid molecule. 7a-Hydroxy-cholestene-3-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
