Problem Set 3

1.  Draw the reaction (by showing all atoms and bonds for both reactants and products) for forming two dipeptides that can be made from  phenylalanine and leucine.  Draw an arrow between the two specific reactant atoms central to this process and show their respective partial charges.

2.  For the formation of glucose-6 phosphate from glucose and phosphate:

   a.  Draw the reaction and explain why this reaction occurs.

   b.  Explain why this reaction  prevents diffusion of glucose from the cell.

  c.  Predict whether this reaction requires or releases energy and clearly explain why.

3. Draw the molecular structure for methyl salicylate and identify a set of two reactants that could be used to synthesize it.
