  1. Composed primarily of carbon, hydrogen, and oxygen atoms and range in size from small to very large.
    Carbohydrates
  2. Large carbohydrates are composed of numerous, relatively simple building blocks (simple sugars)
    Monosaccharides
  3. Composed of two simple sugars bound together through a dehydration reaction.
    Disaccharides
  4. Consist of many monosaccharides bound together to form long chains that are either straight or branched.
    Polysaccharides
  5. A second major group of organic molecules common to living systems.
    Lipids
  6. Consists of a straight chain of carbon atoms with a carboxyl group attached at one end.
    Fatty acids
  7. A 3-carbon molecule with a hydroxyl group attached to each carbon atom.
    Glycerol
  8. Contains only single covalent bonds between the carbon atoms.
    Saturated fatty acid
  9. Has one more double covalent bonds between carbon atoms.
    Unsaturated fatty acid
  10. Differ in chemical structure from other lipid molecules, but their solubility characteristics are similar.
    Steroids
  11. Similar to triglycerides , except that one of the fatty acids bound to the glycerol is replaced by a molecule containing phosphate and usually nitrogen.
    Phospholipids
  12. Constitute 95% of the fats in the human body.
    Triglycerides
  13. The polar end of the molecule is attracted to water and is said to be…
    Hydrophilic
  14. The nonpolar end is repelled by water and is said to be…
    Hydrophobic
  15. What are the building blocks of a polysaccharide?
    Monosaccharides
  16. What are the building blocks of lipids?
    Fatty acids
  17. What are the three groups of lipids?
    Steroids, cholesterol, triglyceride
  18. What is unique about the structure of a phospholipid?
    Phosopholipids have both a hydrophilic (water loving) and hydrophobic (water hating) region. This enables them to effectively make a barrier between the fluid inside and outside of the cell.
