Did you know? Catalyst Rank the following foods, with the food you think is healthiest as number 1 and the unhealthiest as number 8. Whole wheat bread Crunchy Peanut Butter Orange Juice Cheetos Bagel Turkey breast Soy beans Chocolate chip cookie ___ Whole wheat bread ___ Crunchy Peanut Butter ___ Orange Juice ___ Cheetos ___ Bagel ___ Turkey breast ___ Soy beans ___ Chocolate chip cookie Are we what we eat? Macromolecules monomer – monomer – monomer polymer/macromolecule Monomers: Molecules that link to make macromolecules/polymers. Macromolecule: A big, biological molecule Macromolecules 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 Carbohydrates Macromolecule/Polymer: Carbohydrate / Polysaccharide Monomer: Monosaccharide Monosaccharide Carbohydrate / Polysaccharide Function: Store short term energy Food Sources: Sugar (simple carbs), Grains (complex carbs SIMPLE VS. COMPLEX CARBS SIMPLE CARBS COMPLEX CARBS Simple carbs are easily and quickly digested (sugar rush) Complex carbs take longer to digest but still provide short term energy Also known as simple sugar Also known as starch Get their name because they are made up of only one or two sugars Get their name because they are made up three or more sugars Examples: table sugar, soda, candy Examples: bread, pasta, grain Carb-Loading Lipids Macromolecule/Polymer: Lipid Monomer: Glycerol Molecule + Fatty Acid Tails Zoom-In Lipid Function: Store long term energy, cushioning Food Sources: Oils, Fats Glycerol Molecule Polar / Hydrophilic (Loves Water) Fatty Acid Tails (Any #) Nonpolar / Hydrophobic (Hates Water) Your fat looks like this… Proteins Macromolecule/Polymer: Protein / Polypeptide Monomer: Amino Acids (20 different kinds) Zoom-In H Protein Cys Leu Ser Phe Leu H2N C R COOH Side chain changes for each of the 20 amino acids. Function: Enzymes, Hormones, Structural Support, Cell Communication, Builds muscle Food Sources: Meat, Eggs, Beans, Soy, Milk Make your own protein shake! http://www.youtube.com/watch?v=zZuGs7LML-Q Nucleic Acids Macromolecule/Polymer: Nucleic Acid Monomer: Nucleotides Zoom-In P P Nucleic Acid P Function: store and transmit genetic information Types: DNA, RNA and ATP Nucleotide P Key = Phosphate Group = Sugar = Nitrogenous Base Your Task Your group has 10 minutes to present the facts of your assigned macromolecule in a creative way. You will receive a grade on the quality of your presentation Is the information accurate? Is the information complete? Does everyone in the group have equal participation? Is your choice of presentation method creative and engaging? Examples of possibilities: Skit Poem Song An Example… https://www.youtube.com/watch?v=nt9u7CfVoc4
