1. Biomolecules

2. Biomolecules
Biomolecules are carbon based molecules made by living things.
They can also be called macromolecules.
Macro = large
Micro = small

3. Carbohydrates
Carbohydrates: a molecule that is used by many plants and animals to store energy for a short time.
Examples:
Sugar, and Starch
-ose means that something is a type of sugar. Example: Glucose, Lactose, Fructose

4. Some foods that contain a lot of Carbohydrates
Pasta
Bread
Potato

5. Lipids
Lipids: molecules created and used by animals for long term energy storage, protection, and warmth.
Fat on your body provides you with an extra layer for warmth if its cold
It also protects your brain in case your head gets hit, absorbing the impact
Examples: Fats Oils and Wax

6. Things that contain lipids
Cooking Oils
Butter
Candles

7. Lipid Structure Glycerol
Lipids are made of two parts. A glycerol and fatty acids
Fatty Acids

8. Protein
Protein: the work horse of the biomolecules. These molecules carry out most of the functions of the cell, act as building blocks, and allow organisms to move and do many other things.
Examples: Muscle on animals is mostly protein.

9. Some examples of protein
Same
Meats
Muscle
Note: The meat you eat is just the muscle of some animal. For example, beef is cow muscle.

10. Proteins Proteins are polymers made of amino acids.
Polymer- a molecule composed of many smaller units.
Monomer – the smaller unit contained in a polymer.

11. Proteins Enzymes, a type of protein, controls the rate of reactions.
-ase means that something is an enzyme
Example: Protease, Lactase, Amylase
Example: Lactase is an enzyme that breaks down lactose, a sugar.

13. Nucleic Acids
Nucleic Acids: store genetic information about an organism.
Examples: DNA RNA
DNA (Deoxyribonucleic Acid) is the blueprint for most living things on earth. Those that don’t use DNA use RNA.
Your DNA is unique and only an identical twin or clone will have the same DNA as you.

14. Nucleic Acids
DNA

15. Review Questions Name the four Biomolecules:
Carbohydrate, Lipid, Protein, and Nucleic Acid
What are Carbohydrates used for?
To store energy for later use
What are Nucleic Acids for?
To store genetic information

16. Review Questions What do lipids do for you?
The store energy and help keep you warm.
Give an example of a food where you would find protein.
Any meat

17. Review Questions
Give an example of a food where you would find a lot of carbohydrates.
Potato, bread, pasta, etc
Give an example of food with a lot of lipids.
Pizza, butter, any fatty food.
