1. Biological Molecules

2. What is biochemistry??? Biochemistry The study of matter and the changes in matter Pertaining to life Proteins Carbohydrates Lipids Nucleic Acids

3. Macromolecules Polymer: Very large molecule made from individual pieces Monomer AKA: Subunit

4. Hydrolysis: Breaks apart the polymer into monomers Water needed to break the bond Dehydration Synthesis: AKA: Polymerization Links the monomers together to form the polymer Produces water

5. What do monomers look like? Hydrocarbon: Molecule containing Hydrogen and Carbon Ethane Ethene Ethyne Unsaturated Saturated

6. Molecular Structure CHAIN BRANCH RING

7. Substituted Hydrocarbon Hydroxyl -OH Add –ol suffix to name Creates an alcohol Used to disinfect or as a fuel Methanol Methane

8. Carboxyl Group -COOH Creates a carboxylic acid or organic acid Found in citrus fruits, vinegar (ethanoic acid) Methane Methanoic Acid
