Macromolecules Monomers: Molecules that link to make

macromolecules/polymers.

4 Main Macromolecules

“one” “many”monomer – monomer – monomer

polymer/macromolecule

Class Polymer/Macromolecule Monomer

Carbohydrates

Carbohydrate / Polysaccharide

Monosaccharide

Lipids Lipid Glycerol Molecule + Fatty Acid Tails

Proteins Protein / Polypeptide Amino Acids

Nucleic Acids

Nucleic Acid Nucleotides

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 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

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”.

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

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

Atoms Molecules Monomers Macromolecules/Polymers

Cells OrganismsProtonsElectronsNeutrons

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
