1. Macromolecules
Day 2

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?

3. Centrum: Why do we need to feed our cells?

4. 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

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

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

7. 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)

8. 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

9. 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.

10. 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
