Description3-dehydro-4-methylzymosterol belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 3-dehydro-4-methylzymosterol is considered to be a sterol lipid molecule. 3-dehydro-4-methylzymosterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
