1. A Unit on Biomolecules Carbohydrates, Proteins, Lipids & Nucleic Acids
You Are What You Eat!
A Unit on Biomolecules
Carbohydrates, Proteins, Lipids & Nucleic Acids

2. What are organic compounds?
most matter in your body is made of organic compounds
organic compounds contain carbon
carbon atoms covalently bond to other elements like H and O
large compounds of linked carbohydrates, proteins, lipids, and nucleic acids are called polymers

3. OBJECTIVE
SWBAT Compare the chemical structures of carbohydrates, lipids, protein, and nucleic acids, and relate their importance to living things.

4. Dissecting A Nutrition Label
Fats
Carbohydrates
Protein
Vitamins & Minerals

5. What are organic compounds?
most matter in your body is made of organic compounds
organic compounds contain carbon
carbon atoms covalently bond to other elements like H and O

6. Polymers
large compounds of linked carbohydrates, proteins, lipids, and nucleic acids are called polymers
These large organic compounds are called biomolecules.

7. 4 organic compounds found in the human body
Take Notes!
Topic: Biomolecules

Lipids
Proteins
Nucleic Acids
*All are polymers
*All are organic (C) compounds
4 organic compounds found in the human body

8. BIOMOLECULE MADE OF… EXTRA INFO EXAMPLES CARBOHYDRATES
(sugars and starches)
LIPIDS/FATS
PROTEINS
NUCLEIC ACIDS

9. 1. Carbohydrates

10. CARBOHYDRATES
STARCHES
Long Term Energy
SUGARS
Quick energy

11. Carbohydrates (Made of…)
A biomolecule composed of Carbon, Hydrogen, and Oxygen.
Glucose (sugar) is a Carbohydrate
Ratio:
C6H12O6

12. Examples of Carbohydrates
Fruits, vegetables, and grains

13. 2. Lipids / Fats

14. Lipids (Fats) made of… Take Notes! Made of C, H, & O in chains
Examples: found in oils, butter, soaps & waxes

15. 3. Proteins

16. What Do Proteins Look Like?
The building blocks of Proteins are amino acids.
*Unlike Carbohydrates, proteins contain Nitrogen.  Extra info

17. Proteins (extra info)
Needed for the growth and repair of body tissues

18. Where can we find proteins in living things?
1.) hair
2.) finger nails
3.) horns
4.) hoofs

19. Examples of Proteins
Meat, egg, dairy, seeds, nuts, & beans

20. 4. Nucleic Acids

21. Nucleic Acids Take Notes! Examples: DNA or RNA Made of nucleotides
Carry genetic information in cells
Examples: DNA or RNA
Nucleic Acids

22. Nucleic Acid Structure
Nucleic acids are made up of nucleotides
DNA (deoxyribonucleic acid) – carries genetic information
RNA (ribonucleic acid) – makes proteins

23. OBJECTIVE
SWBAT differentiate between the four biomolecules (carbohydrates, lipids, protein, and nucleic acids) by testing for their presence in the components of a Big Mac burger.
