Document Summary
Objective 1 specify the chemical and physical properties of water. Inorganic compound made up of one oxygen and two hydrogen molecules. Held together by a single covalent bond. The slight negative and slight positive charge makes water a polar molecule. Objective 2 explain the biological importance of water: the most abundant of all substances in the body. It is found in most tissues such as 60% of rbc"s, 75% of muscles, and 92% of blood plasma: universal solvent and suspending material; materials necessary for health and survival of the body are dissolved in water. They travel, dissolved in the blood plasma, through the circulatory system, and diffuse, dissolved in water, through the tissue fluid and into and out of cells. Many organic molecules (i. e. , amino acids and glucose) dissolve in water, and many other inorganic molecules such as salts. It acts as a raw material in many chemical reactions.
