The Biological Importance of Water Water is a very simple and important molecule, which is fundamental to the survival of life on earth. Well known in the format formula of H20, with 2 hydrogen atoms bonded with one oxygen atom. Active living cells are composed of two thirds or more of water, as is the area that covers the earth currently. Water is a very unique molecule, as it is the only substance, which can be found naturally occurring as a gas (vapour), liquid and a solid (ice). Water molecules are bonded together by action of hydrogen bonding; this special bonding is what makes water so special. The intermolecular forces are much larger for a molecule of it's relative molecular mass (18) which is why it remains as a liquid at room temperature, unlike similar molecules such as Methane (16) and Ammonia (17) which are all gases at room temperature. This results...
