Building from the bottom

1. Carbon

• atomic bases of life
• likes to make chains of atoms

2. Carbon + Hydrogen

• Hydrocarbon
• oil and gas - energy
  • simple examples
    • 1 - ethane
    • 2 - methane
    • 3 - propane
    • 4 - butane
    • 5 - pentane
    • 6 - hexane

3. Carbon + hydrogen + water

• hydrocarbon + water
• oxygenated hydrocarbon
  • little bit water
    
    • Hydrated hydrocarbon --> fatty acid
  • lots of water
    
    • Hydrated hydrocarbon --> carbohydrate

Definition: Carbohydrate

Definition: fatty acid

Carbohydrate VS. Fatty acid

• Carbohydrate
  • example
    • six carbon sugar
    • table sugar, sucrose
    • hex- means six
    • hexose, a six carbon sugar
      • fructose
      • glucose
      • galactose
• Fatty Acid
  • example

Sugar VS. Lipid

Vrrrrooom.....tada -- Lipid

1. a group of substances
2. carbon+hydrogen+oxygen
3. carbon is 'oily'
4. carbon overpowers the hydration part
5. dehydrated carbohydrate
6. fatty, greasy, oily, and waxy
7. cannot mix into water (insoluble in water)

Simple lipids

• triglycerides
• neutral fats
• the grease of life and membranes
• compartmentalizes water in areas
• keeps fluids from mixing together
• separates fluids
• cells
• arteries
• cavities
• bladders

triglyceride

• one molecule of glycerol
• joined to three fatty acids
• tri- means 3-
• glyceride, a derivitive of glycerol

glycerol

• an alcohol - OH, included
