DescriptionCholesterol belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Cholesterol is an extremely weak basic (essentially neutral) compound (based on its pKa). Cholesterol is a potentially toxic compound.
