The suffix "-ane" is used in chemistry to indicate a saturated hydrocarbon. This means that the molecule contains only single bonds between carbon atoms and is completely "saturated" with hydrogen atoms.
Here are some examples:
* Methane: CH4
* Ethane: C2H6
* Propane: C3H8
* Butane: C4H10
These molecules are all alkanes, which are the simplest type of hydrocarbon.
