Transcript

  • 1. Launch
    • Write the monomer and polymer names for the four types of macromolecules
  • 2. Macromolecules
    • Day 3
  • 3. Carbohydrates
    • Made of carbon, hydrogen, and oxygen
    • Used as main energy source for living things
    • Sometimes used as structural support
      • Plant walls and exoskeleton
  • 4. Building carbohydrates
    • Carbohydrates= forms of sugars
    • Carbohydrates have the ability to store the most amount of energy per gram out of all the macromolecules
  • 5. Structure of a Carbohydrate What do you notice about this structure?
  • 6. Rings connect to form polysaccharides (polymer / macromolecule)
  • 7. Lipids
    • Examples:Fats, waxes, oils
    • Made mostly of carbon and hydrogen
    • Used to store energy
    • Hydrophobic=scared of water
  • 8. Building lipids
    • Made of 3 fatty acids attached to glycerol
    • Different types of fats
      • Saturated fats (ex. butter)
      • Unsaturated fats (ex. oil)
    Glycerol Fatty Acid Fatty Acid Fatty Acid
  • 9. Proteins
    • Some help chemical reactions happen faster (enzymes)
    • Some help support cell structure
    • can also be used for energy
  • 10. Proteins
    • Made from DNA and RNA
    • Order of monomers is extremely important
  • 11. Building proteins
    • Made up of amino acids
    • Different order of amino acids = different proteins
    • Must be folded correctly to work
  • 12. Nucleic Acids
    • Stores and passes along genetic material
    • 2 types: DNA and RNA
    • Made of strands of nucleotides , which have a base made of nitrogen
    • Order of monomers is extremely important
  • 13. Building nucleic acids
    • The building blocks of nucleic acids are nucleotides
