Sep 29, 2015 · Water molecules are essential to the functioning of most known life-forms because of water's unique chemical properties, researchers say.
Water, like carbon, has a special role in living things: it is needed by all known forms of life. Although water consists of simple molecules, each containing just three atoms, its structure gives it unique properties that help explain why it is vital to all living organisms.

For the thousands of chemical reactions going on in our cells to happen quickly and efficiently, the molecules involved need to be able to mix freely – they need to be dissolved in something. Water is so good at dissolving substances that it is known as the ‘universal solvent’.
Virtually all chemical reactions in life processes take place in solution in water. Some organisms can live in a dormant and desiccated state for long periods of time but require water to become active. Water is present both inside and outside cells.
Jul 31, 2022 · Water is one of the more abundant molecules in living cells and the one most critical to life as we know it. Approximately 60–70 percent of your body is made up of water. Without it, life simply would not exist. Water Is Polar. The hydrogen and oxygen atoms within water molecules form polar covalent bonds.
Jan 23, 2021 · Our understanding of water's role in the reactions of life is being overturned. WATER is essential for life as we know it, but why? A new analysis may rewrite the idea that it is solely the medium in which the reactions that drive life occur, instead viewing it as an active participant.
