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

Macromolecules

 Monomers: Molecules that link to make macromolecules/polymers.

“one” “many” monomer – monomer – monomer polymer/macromolecule  4 Main Macromolecules

Class Polymer/Macromolecule Monomer

Carbohydrates Carbohydrate / Polysaccharide Lipids Lipid Monosaccharide Glycerol Molecule + Fatty Acid Tails Proteins Nucleic Acids Protein / Polypeptide Nucleic Acid Amino Acids Nucleotides

Macromolecules

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

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

Macromolecules

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

Macromolecules

  Protein / Polypeptide (Macromolecule) Amino Acids (Monomer) Zoom-In H H 2 N C COOH Protein    Leu Phe Leu Ser Cys R Side chain changes for each of the 20 amino acids.

Function: Enzymes, Hormones, Structural Support, Cell Communication Food Sources: Meat, Eggs, Beans, Soy, Milk Connections: Protein powder to “build muscle”.

Macromolecules

  Nucleic Acid (Macromolecule) Nucleotides (Monomer) Zoom-In P P Key = Phosphate Group = Sugar (“-ose” = Nitrogenous Base P P Image Source: www.astrochem.org

Nucleic Acid Nucleotide

Macromolecules

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

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

Cells

 Levels of Organization Protons Electrons Neutrons Atoms Molecules Monomers Macromolecules/ Polymers  Cells: A.

B.

C.

All life has ≥1 cell(s) Basic unit of life (anything before is not living) Cells come from other living cells Cells Organisms

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.

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
