Common Name | 5alpha-Cholestanone |
---|
Description | 5alpha-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. |
