					           Introduction to Organic Molecules (Biochemistry)
                      The Molecule of Life

1. “Organic” means a molecule contains: CARBON
         a. Exceptions CO2 and CO (Carbond Dioxide/Carbon Monoxide)
         b. Organic food-no pesticides
         c. Organic means “living”
         d. Contain carbon and are found in living tissue
                (Carbs, Proteins and Lipids are examples)

   “Inorganic” means a non-carbon based molecule

2. Since Carbon has 4 valence electrons it can make 4   bonds.
              Carbon loves to bond
              Carbon can form long chains or rings




3. These bonds allow it to make long chains and rings

4. Carbons with different elements joins to make   MACROMOLECULES
         or larger molecules.
                 “MACRO”-means big

   4 MAJOR types of Macromolecules/Organic Molecules
         a.) Carbohydrates

          b) Lipids

          c.) Proteins
        d) Nucleic Acids

  Functional Groups- A group of atoms that react in predictable ways.
        c-c-c-c-c-c
        When you add stuff to the sides you make a different molecule

5. POLYMER AND MONOMER

  Polymerization-the stringing together of small molecule units in order
  to make a larger molecule

  Many of the macromolecules are made of repeating small units called
        MONOMERS-“building blocks”
        “Mono”=one

  Dimer-two molecular units joined together

  When the monomer units come together they make long chains called
  POLYMERS
        “Poly”=more than one
Dehydration Synthesis-each time a monomer is added to a chain water
must be removed.

      “Synthesis”-means to make something




Hydrolysis -water MUST be added to break down a polymer
     - “Hydro”-means water
     - “ lysis”-means to break

“Hydrolysis”-The process by which water is added to break down the chains
of macro-molecules.
