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
