Document Summary
Water covers 70. 9% of the earth"s surface, and is vital for all known forms of life. Water is vital both as a solvent in which many of the body"s solutes dissolve and as an essential part of many metabolic processes within the body. The study of chemical reactions occurring in animals, plants and microorganisms. Water is the solvent for both intracellular and extracellular chemical reactions. Water accounts for 78% of baby and 60% of the body weight of an adult. 37% is in the extracellular fluid, about 1/4 being blood plasma. Brain: 70% water; lungs: 90%; lean muscle: 75%; bone: 22%; blood: 83% Deviations of more than 1 or 2% from the normal can have deleterious effects (e. g. cholera). Water has very special physical and chemical properties, which are essential to understand the chemical structure, conformation and function of biomolecules. > these properties determine the chemistry of biology:
