Glucose Model
Questions

  1. What are common features to all amino acids?
    (Water)
  2. Compare and contrast the composition of an amino acid to a sugar.
    (The "open" bonds from neighboring sugars join together and link the side-by-side sugars into a dissacaride)
  3. From what you can observe in the molecular structure, can dehydration synthesis also produce long chains of amino acids? Explain.
    (Water would cause neighboring sugars to unlink in a reverse reaction to dehydration synthesis)

Saturated and Unsaturated Fats
Questions

  1. When saturated, how many different atoms can a carbon bond to?
    (four)
  2. What must be added to an unsaturated chain, in order to make it saturated?
    (hydrogen)
  3. Infer the structural feature of a "polyunsaturated fat".
    (The fat molecule has more than one double bond in its structure).
