A number of biochemistries alternative to the terrestrial CHON biochemistry are possible in non-aqueous environments that might exist elsewhere in space.
Molecular dynamics simulations suggest that membranes composed of acrylonitrile could form vesicle-like structures in liquid methane.
Solvents other than water have different temperature ranges in which they exist in the liquid phase. This property has the potential of extending the “habitable zone” to distances other than that available to aqueous environments.
Chemical species in liquid phase over different temperature ranges than water.
