1. A Macromolecule Investigation

2. What Are Macromolecules? Monomer Polymer

3. What are monomers that make them?  4 main monomer types  Saccharides  Amino Acids  Fatty acids  Nucleotides

4. What polymers do they make?  Saccharides  Polysaccharides, carbohydrates, fiber, sugars  Amino Acids  Proteins  Fatty Acids  Lipids, fats  Nucleotides  DNA and RNA

5. What do macromolecules do?  Polysaccharides: Energy storage (carbs), structural support (fiber in plants)  Proteins: Cellular machinery (enzymes), cell communication  Lipids: Energy storage, cellular membranes  DNA: Instructional database, like a computer code

6. Today: Focus on carbohydrates and lipids  Station 1: Determine fat content of bacon and compare to food labels  Station 2: Detecting presence of sugars as monomers (simple sugars) or polymers (complex sugars)  Station 3: Measuring the densities of lipids
