The Physical Science of Water

Water is a remarkable substance. If we ourselves were not composed mainly of water, and the substance had only been discovered recently, we might consider it to be the most exotic substance on Earth. It seems ordinary only because we are so familiar with it. 

The structures that make up cells are possible because of the structure of water itself. Water allows cells and their components to take shape. It speeds up chemical reactions in cells and water itself or its ions are directly involved in a great many essential biochemical reactions, as either reactants or products.
