1. Organic Compounds & Energy Transformations

2. Chemical Formulas Example: C6H8O6 (Vitamin C)
C, H, O = symbol for element, C = Carbon, H = Hydrogen, O = Oxygen (Capital letter or capital & lower case letter)
6, 8, 6 = Number of atoms of the element (C = 6, H = 8, O = 6)

3. Organic Compounds
Must contain the element carbon (Symbol = C)
Example = Cholesterol C27H46O

4. Organic Compounds
Carbon is found in pencil lead, diamonds, graphite, coal, etc.

5. Organic Compounds
Can also contain Hydrogen (H), Oxygen (O), Nitrogen (N), Sulfur (S), Phosphorous (P), etc.
Example = Acetaminophen C8H9NO2 P

6. Inorganic Compounds Do not contain Carbon (C) Example = Rust Fe2O3
Only has Fe (Iron) & O (Oxygen)

7. Organic or Inorganic? Caffeine C8H10N4O2 Stomach Acid HCl
Aspirin C9H8O4
Drano NaOH
Salt NaCl
Sugar C12H22O11

8. Energy Transformations
Chemical energy in the body is changed into: heat energy, kinetic or mechanical energy, electrical energy, & sound energy.

9. Proteins, Fats, & Carbohydrates
These are the Nutrients our body needs to stay healthy
All are organic compounds
Carbohydrates and fats give energy
Body uses Protein to make new tissues like skin and muscles.
