Organic Chemistry The chemistry of living things (CARBON BASED)

Carbohydrates  Building Block: simple sugars (glucose)  Purpose: ENERGY!  Found in: bread, starches  Extra Information:  Can be simple or complex  MONOSACCHARIDES – SINGLE SUGAR  DISACCHARIDES – TWO SUGAR MOLECULES  POLYSACCHARIDES – MANY SUGARS

Proteins  Building Block: amino acids  Purpose: regulate chemical reactions, hemoglobin – delivers oxygen in blood, hair and nail growth  Found in: meat, eggs, cheese  Extra Information:  Proteins are made of 20 different amino acids, 9 of which CANNOT be created in your body – you have to eat them!

Lipids  Building Block: fatty acids  Purpose: long term energy storage, cell membranes (phospholipids)  Found in: fast food, baked goods  Extra Information:  Lipids do not dissolve in water  Stored in animals as fat (solid)  Stored in plants as oil (liquid)

Nucleic Acids  Building Blocks: Nucleotides  sugar + base + phosphate  Purpose: Storage of Genetic Information  Found in: Every cell  Extra Information:  Two Types  DNA = deoxyribonucleic acid – genetic info  RNA = ribonucleic acid – protein synthesis
