Inorganic Acids, Bases, and Salts Ionization (dissociation)- the breaking apart of the inorganic molecule when dissolved in water Acid - a substance that dissociates into H + and negative ions (anions) Base - a substance that dissociates into OH - (hydroxide) ions and a positive ion (cation) Salt - a substance that dissociates into a cation and anion, neither of which is H + or OH - Maintaining pH: Buffer Systems Compounds that prevent drastic changes in pH or Acid/Base balance * Normal body pH is between 7.35 and 7.45 * acid base balance depends on the hydrogen ion concentration * majority of hydrogen ions are produced by the metabolic activity of the cell the CO 2 of respiration combines with water to form carbonic aced which dissociates into hydrogen and bicarbonate ions CO 2 + H2O H 2 CO 3 H + + HCO 3 - Buffers Hydrogen ions can also be introduced into the body by other chemical compounds that we consume (whether nutritious or caustic). Buffer Systems consist of weak acids and weak bases that function to prevent drastic changes in

Systems That Control pH * Respiratory System * Urinary System Buffers Principal buffer systems * carbonic acid-bicarbonate system * phosphate system * hemoglobin system * protein system Organic Compounds Macromolecules * Four major organic compounds of the body * carbohydrates * lipids * proteins * nucleic acids Organic Compounds Macromolecules * Most of the macromolecules are made up of smaller monomer units to form polymers * Dehydration reaction- building up * Hydrolysis reaction- breaking down Dehydration Synthesis Combines Monomers into Polymers Hydrolysis Breaks Polymers Into Monomer Units Carbohydrates * Starches and sugars * main use as energy source * composed of a carbon, hydrogen and oxygen * oxygen to hydrogen ratio is 1:2 * multiple of CH 2 O Ex. Glucose (C 6 H 12 O 6 ) Forming Fructose From Glucose and Fructose...
