Although all living things on Earth (including methanogens) use liquid water as a solvent, it is conceivable that life on Titan might instead use a liquid hydrocarbon, such as methane or ethane.[28] Water is a stronger solvent than hydrocarbons,[29] however, water is more chemically reactive, and can break down large organic molecules through hydrolysis.[28] A life-form whose solvent was a hydrocarbon would not face the risk of its biomolecules being destroyed in this way.[28]
