  1. Organic molecules:
    • carbon, hydrogen and oxygen
    • -CARBON CORE - others attach (chemical properties)
  2. Functional groups:
    attached to carbon core
  3. 4 kinds of organic molecules (large)
    • large=macromolecules
    • -most are polymers made of building blocks (monomeres)
  4. Dehydration synthesis:
    take water off to put things together
  5. Hydrolysis:
    Water to break apart
  6. Carbohydrates:
    • Carbon, Hydrogen and Oxygen
    • -sugars, starches, wood *energy storage/structural
    • -monomeres
    • -polymeres
  7. monosarcharides:
    • 3-7 carbons
    • Hexoses - 6 carbons (glucose)
    • Pentoses - 5 carbons (Deoxyribose)
  8. Disacharides:
    • monomere + monomere --> disacharides + H20 (takes energy = endergonic)
    • H20 +disacharide --> monomer + monomer (hydrolosis) (gives off energy = exergonic)
  9. sucrose:
    disacharide - main sugar plants transport
  10. Polysaccharide:
    • chains of glucose
    • 1) starch - plants-
    • animals -
    • 2) cellulose- plants (structural element) string of glucose attached in a diff. way.
    • 3) chitin - (insects/fungi) long chain of glucose (provides insects w/ exoskeleton)
  11. Lipids:
    • fats, oils
    • -lots of energy contained
    • -not H20 soliable
  12. Types of lipids:
    • 1) fatty acids
    • 2) fat / oil molecule
    • 3) phospho lipids
    • 4) steroids
  13. Fatty acids:
    • building block for bigger ones
    • c-c-c-c c
    • c=fatty acid (others attach to it)
  14. Fat / oil molecules:
    • triglycerides
    • energy storage
  15. phospho lipids:
    • c-c-c
    • one of the c's is phosphate containing part
    • help make up cell membrane
    • End of phophate containing part - hydrophilic/polar
  16. polar / non polar:
    • hydrophilic
    • hydrophobic
  17. steroids:
    animal hormones, cholesterol
