  1. Organic Molecules
    carbon-based molecules
  2. Inorganic Molecules
    non-carbon-based molecules
  3. Hydrocarbons
    organic molecules composed of only carbon and hydrogen atoms
  4. Functional Group
    group of atoms w/in a molecule that interacts in predictable ways w/ other molecules
  5. Hydrophilic
    attract water molecules
  6. Monomers
    small molecular unit: building block of a larger molecule
  7. Polymers
    long chains of monomers
  8. Molecule categories
    • carbohydrates
    • lipids
    • proteins
    • nucleic acids
  9. Lipids
    • water-avoiding compounds (hydrophobic)
    • act as boundary that surrounds/contains the aqueous contents of cells
    • Certain types: Fats, Steroids
  10. Fat
    • organic compound made up of a 3-carbon backbone (glycerol) attached to 3 fatty acids
    • store energy for later use
    • cushion organs
    • provide insulation
    • Certain types: Saturated, unsaturated
  11. Oils
    fats that are liquids at room temperature
  12. Saturated fat
    • fat where all 3 fatty acid chains contain the max. # of hydrogen atoms
    • solid at room temp.
    • (carbon atoms single bonded)
  13. Unsaturated fats
    • contain less than max. # of hydrogen atoms in 1 or more of its fatty acid chains
    • (carbon atoms double-bonded)
  14. Steroids
    • lipid molecules w/ 4 fused carbon rings
    • Some circulate body as chemical signals (estrogen, testosterone)
    • Certain type: Chloresterol- in plasma membrane of animal cells; starting point from which your body produces other steroids
