Introduction to Basic Chemistry * 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 Lipids * Composed of carbon, oxygen, and hydrogen
