More ratios. Through the use of nuclear magnetic resonance
spectroscopy, it is possible to determine the ratio between the
protonated and deprotonated forms of buffers. (a) Suppose the ratio
of [ A- ]A I to [HA] is determined to be 0.1 for a buffer with
pKar6.0.pKa = 6.0. What is the pH? (b) For a different buffer,

suppose the ratio of [ A- ]lA J to [HA] is determined to be 0.1 and
the pHpH is 7.0. In this case, what is the pKapKa of the buffer? (c) For
another buffer with pKa=7.5PKa = 7.5 at pH 8.0pH 8.0, what is the
expected ratio of [ A- ][A ] to [HA]? do

Which statements are true?
The protein is active when one asp residue is protonated and the other is deprotonated.
O Both asp residues are protonated at more basic pH values.
O Active aspartyl proteases have only one asp residue in the active site.
Only one asp side chain is protonated at low pH (below pH 3.5).
Both asp side chains are deprotonated at higher pH values.
Sweet proteins. List the key classes of glycoproteins, their defining characteristics, and their biological functions.

- Ionization State of Histidine.Each ionizable group of an amino acid can exist in one of two states, charged or neutral. The electric charge on the functional group is determined by the relationship between its pKa and the pH of the solution. This relationship is described by the Henderson-Hasselbalch equation. 1.Histidine has three ionizable functional groups. Write the equilibrium equations for its three ion-izationsand assign the proper pKa for each ionization. Draw the structure of histidine in each ionization state.What is the net charge on the histidine molecule in each ionization state? 2.Which structure drawn in (1) corresponds to theionization state of histidine at pH 1, 4, 8, and12?Note that the ionization state can be approximated by treating each ionizable group independently. 3.What is the net charge of histidine at pH 1, 4, 8, and 12?
