1 Catalyst  Rank the following foods, with the food you think is healthiest at the top and the unhealthiest at the bottom.  Whole wheat bread  Crunchy Peanut Butter  Orange Juice  Cheetos  Bagel  Turkey breast  Soy beans  Chocolate chip cookie

2 Macromolecules  Monomers: Molecules that link to make macromolecules/polymers.  4 Main Macromolecules “one”“many” monomer – monomer – monomer polymer/macromolecule ClassPolymer/MacromoleculeMonomer CarbohydratesCarbohydrate / PolysaccharideMonosaccharide LipidsLipidGlycerol Molecule + Fatty Acid Tails ProteinsProtein / PolypeptideAmino Acids Nucleic AcidsNucleic AcidNucleotides

3 Macromolecules  Carbohydrate / Polysaccharide (Macromolecule)  Monosaccharide (Monomer)  Function: Store short term energy  Food Sources: Grains (carbohydrate), Candy (Monosaccharide)  Connections: “Carb-Loading” before a race. Carbohydrate / Polysaccharide (“Complex Carbs”) Monosaccharide (“Simple Carbs”) Glucose Molecule “Sugar”

4 SIMPLE VS. COMPLEX CARBS  Simple carbs are easily and quickly digested  Also known as simple sugar  Get their name because they are made up of only one or two sugars  Examples: table sugar, soda, candy  Complex carbs take longer to digest  Also known as starch  Get their name because they are made up three or more sugars  Examples: bread, pasta, grain

5 Carb-Loading 

6 Macromolecules  Lipid (Macromolecule)  Glycerol Molecule + Fatty Acid Tails (Building Blocks)  Function: Store long term energy, cushioning  Food Sources: Oils, Fats, Waxes  Connections: Fat cells synthesize & breakdown lipids Lipid Zoom-InGlycerol Molecule Polar / Hydrophilic (Loves Water) Fatty Acid Tails (Any #) Nonpolar / Hydrophobic (Hates Water)

7 Your fat looks like this…

9 Macromolecules  Protein / Polypeptide (Macromolecule)  Amino Acids (Monomer)  Function: Enzymes, Hormones, Structural Support, Cell Communication  Food Sources: Meat, Eggs, Beans, Soy, Milk  Connections: Protein powder to “build muscle”. Protein Leu PheLeu Ser Cys Zoom-In H2NH2NCCOOH H R Side chain changes for each of the 20 amino acids.

10 Make your own protein shake! 

11 Macromolecules  Nucleic Acid (Macromolecule)  Nucleotides (Monomer) Zoom-In P P P Nucleotide Nucleic Acid P = Phosphate Group = Sugar (“-ose” = Nitrogenous Base Key Image Source:

12 PPP ATP Break this bond for ENERGY! Macromolecules  Nucleic Acid (Macromolecule)  Nucleotides (Monomer)  Function: Store and transmit genetic information; “blueprints”  Examples:  DNA (deoxyribonucleic acid)  RNA (ribonucleic acid)  ATP (adenosine triphosphate) deoxyribose sugar ribose sugar Nucleic Acids Nucleotide

14 Macromolecule Stations  4 stations  Simple carbs  Complex carbs  Protein  sugar  Fill out the table for the station you’re assigned, and then rotate (after approval from Ms. Adabale)  You have about 7 minutes at each station

15 Cells  Levels of Organization  Cells: A. All life has ≥1 cell(s) B. Basic unit of life (anything before is not living) C. Cells come from other living cells AtomsMoleculesMonomersMacromolecules/ Polymers CellsOrganisms Protons Electrons Neutrons

16 Scavenger Hunt  You are working with your table  You have 15 minutes to get as much done as you can.  As soon as you’re done, or after 15 minutes (whichever comes first), come back to class.

17 Homework  Create a book of Macromolecules  Fold 3 sheets of letter-sized paper horizontally  First page should include your name, period, and date  Dedicate 2 pages/macromolecule  Pages must include: polymer and monomer name, picture of polymer and monomer, function, and at least 2 examples  Make it colorful!  Decorate the cover of your book
