The properties of water that make it biologically important are its molecular polarity, thermal stability (elevated specific heat), fusion and boiling points that allow it to remain liquid in most environments, acid-base neutrality, small molecular size and low chemical reactivity. (This is compared to other substances, such as ethanol or hydrogen sulfide.)
