The Biological Importance of Water

Water is a polar molecule, which means it has beas of roughly and sparingly disal slump aras of charge. This is because of the electronegativity of hydrogen and of atomic number 8. negativeness is the ability of an decline cell to attract electrons in a covalent bond. In water, oxygen has a much prouder(prenominal) electronegativity, so the shared electrons are attracted more or less more towards the oxygen, making the oxygen slightly negative and the two hydrogens slightly positive. adjacent water molecules are attracted to separately another(prenominal), forming hydrogen bonds between the slightly positive hydrogen and the lonely(prenominal) pairs of electrons from the oxygen. Hydrogen bonds are quite truehearted compared to other intermolecular forces, allowing the water to be very stable. This gives it a high change state heighten and a high SHC. Each water molecule has the potential to form 4 hydrogen bonds which makes the boiling point much higher than othe r hydrogen bonded compounds. Water sticks to itself collectible to the polarity, and this is called cohesion. However, another property of it is esteem, which is usually stronger than the cohesive forces. This is why it spreads unwrap on erupts like glass, as it is more attracted to that than itself. The polarity too allows water to act as a solvent, giving it the byname of the universal solvent.

These properties allow many biological functions to ask place. In demonstrates, many molecules including hormones and sugars are transported in solutions. Cohesion and adhesion allow this to take place as the wat er sticks to itself and the walls of the tub! e, and its low viscosity allows it to flow through. Water is a good surround for chemical reactions such as photosynthesis and public discussion because of its thermal stability and solvent properties. It is also essential in keeping plant cells turgid, which is authorised so the plant has a large surface area for photosynthesis. Water is also important in animals. entirely transport fluids such as blood and cytoplasm are water based, and...If you want to get a full essay, army it on our website: OrderCustomPaper.com
