Gonane

Tetracyclic hydrocarbon parent of the steroids

Gonane (cyclopentanoperhydrophenanthrene) is a chemical compound with formula C17H28, whose structure consists of four hydrocarbon rings fused together: three cyclohexane units and one cyclopentane. It can also be viewed as the result of fusing a cyclopentane molecule with a fully hydrogenated molecule of phenanthrene, hence the more descriptive name "perhydrocyclopenta[a]phenanthrene". The non-systematic version of the above name is "cyclopentanoperhydrophenanthrene".
