a) Show all the possible hydrogen bonds and acceptors of the structure amino acid (Arginine)

b) Draw water that is forming a hydrogen bond with optimal geometry with the amino acid arginine

c) Draw the titration curve for the amino acid glycine on the graph below

d) Indicate the Ph ranges in which one could make an effective buffer using glycine.

e) Solution A consists of 0.2 M of the uncharged species of glycine. Solution B consists of 0.2 M monosodium glycine (which yields glycine with a -1 charge when dissolved. If you make a total of 1 L of a 0.2 M glycine buffer with a ph of 9.1, what volume of each solution should you mix together?
