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
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”
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 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.

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