1. Biological Macromolecules
You are what you eat.

2. Background Information:
“Biological Macromolecule” means the large molecules that all living things contain.
Four categories
Carbohydrates
Lipids
Proteins
Nucleic Acids

3. Carbohydrates Examples: Subunits: Bread Rice Corn Pasta
Monosaccharides

4. Carbohydrates Uses: Found in cells: Rapid energy source for cells
Structural building material in plants
Found in cells:
Cytoplasm
Attached to the outside of cell membranes

5. Carbohydrates
Elements:
Carbon
Hydrogen
Oxygen
Ratio of CH2O

6. Lipids
Examples:
Oils
Butter
Waxes
Subunits:
phospholipids

7. Lipids Uses: Found in cells: Store energy for long periods of time
Form the cell membranes
