Description4,4-dimethyl-5α-cholest-7-en-3β-ol belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 4,4-dimethyl-5α-cholest-7-en-3β-ol is considered to be a sterol lipid molecule. 4,4-dimethyl-5α-cholest-7-en-3β-ol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
