Macromolecules Day 2

Macromolecules Objective: Compare and contrast the basic molecular structure of the 4 macromolecules of life. Essential Question: How do the different Macromolecules meet our needs?

Centrum: Why do we need to feed our cells?

Macromolecules There are four macromolecules of life: Carbohydrates Lipids Protein Nucleic Acid All four have a carbon base and are organic compounds * Follow along and fill out graphic organizer with monomer, structure, function

Carbohydrates – mono/polysaccharides Element: C H O Structure: Rings Function: Quick energy examples: Sugar, starch, -ose

Lipids- fatty acid tails Elements: C H O Structure: chains Function: Long term energy Cell membrane Examples: Fats, waxes, oils, steroids

Protein- Amino Acid Element: Structure: Function: Examples: C H O N (S) Structure: Polypeptide chains (N-C-C) Function: Shape determines the function Examples: Enzymes (end in –ase)

Nucleic Acid- Nucleotides Elements: C H O N P Structure: Double helix Sugar, phosphate, nitrogen base Function: Store and transmit genetic information Examples: DNA RNA

Building Macromolecules C- level 2 voice H- ask three before me A- complete macro packet and puzzle M- remain seated at your assigned seat P- complete the packet and paste in left side of notebook SUCCESS! Work on the packet identifying structure and function of each macromolecule and their monomers. Once you are complete, call Ms Beck and work on completing Macro puzzle.

Macromolecule Structural Models At each part you must… Count the atoms in the molecule. Pick color of the molecule to match your model on the paper. Playdough= elements Toothpicks = bonds
