2. Carbohydrates
An organic molecule that contains C,H,O in a specific ratio
1 CARBON
1 OXYGEN
2 HYDROGEN
The simplest carbohydrates are called monosaccharides or simple sugars
Mono means 1 and saccharide means sugar

3. Carbohydrates as food Sugars (plants) Starches (plants)
Cellulose (plants)
Bread
Cereal

4. Lipids C57H110O6 Commonly called fats and oils
Have an unequal distribution of C-H-O atoms
Example of a common Lipid
C57H110O6

5. Properties of Lipids Insoluble in water (do not mix with water)
Non-polar (unequal distribution of charges)
Animals use them for long term energy storage
Used for insulation and protection

6. Lipids as foods Also called fat/oil
Fat on a steak
Cooking oil
Vegetable oil
Butter
