Natural Product Identification
Common Name5alpha-Cholestanone
Description5Alpha-Cholestanone, also known as 5α-cholestanone, belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 5alpha-cholestanone is considered to be a sterol lipid molecule. 5Alpha-Cholestanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral.
