2. Read Only 1. Carbohydrates (sugars) 2. Lipids (fats)
The 4 Organic Macromolecules found in all living things include:
1. Carbohydrates (sugars)
2. Lipids (fats)
3. Proteins (meats and dairy)
4. Nucleic Acids (DNA)

3. in your notebook, Open to two side-by-side pages
Make sure there is nothing on the back of this page.
If there is, skip that page and find your next page that does not have writing on either side.

4. Fold both pages inward towards the seam of the notebook

5. Write the title and date at the top of both flaps
Divide each flap in half to create 4 sections
Copy the OUTSIDE Labels as shown.
There is nothing else going on the outside of these flaps so write large to fill up the space.
The bottom of each flap identifies the elements that are in each macromolecule.
Contain C, H, O
Contain C, H, O, N, S
Contain C, H, O
Contain C, H, O, N, P

6. Copy this into the INSIDE of the foldable.

7. Use the information on the following slides to fill out the foldable.

8. Carbohydrates are composed of the elements carbon, hydrogen, and oxygen. (CHO)
Function: Cells use carbohydrates to get and store energy.
Examples: Glucose- fruit, vegetables; starches (bread, tortillas, pastas, rice)
Simple Carbs
(better for you)
Large Carbs
(Complex carbs)

9. Lipids are composed of the elements Carbon, Hydrogen, and Oxygen. (CHO)
Function: Unused food/energy is stored in the body as fat (lipids). When fat is broken down, it provides energy for living things. Also, lipids are found in the cell membranes
Examples: Cholesterol, fish oil, nuts, avocados, butter/oils
For Example:
Fish Oil

10. Proteins are large molecules made of carbon, hydrogen, oxygen, nitrogen, and sulfur. (CHONS)
Function: Build organelles (cell parts); it is needed for tissue growth and repair; helps body defend illnesses; allows for chemical reactions to occur within cells.
Examples: Meat, fish, eggs, milk
In living things: Hair and nails contain keratin which is a protein that gives them strength

11. Nucleic Acids are long, repeating chains made of the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus. (CHONP)
Function: Used to store genetic information (DNA) and stores info. that cells need to create proteins.
Examples: DNA. All living things have DNA, so nucleic acids are in ALL foods.
Chromosome
DNA
