A typical amino acid with one amino group and one
- Suggest the forms of the amino acid at low PH and at high pH.
- Amino acids generally have two pKa values, one in the range of 2 to 3 and the other in the range of 9 to 10. Serine, for example, has pKa values of 2.19 and 9.21. Using species such as acetic acid and ammonia as models, suggest the origin of the two pKa values.
- Glutamic acid is an amino acid that has three pKa’s: 2.10, 4.07, and 9.47. Draw the structure of glutamic acid, and assign each pKa to the appropriate part of the molecule.
- An unknown amino acid is titrated with strong base, producing the following titration curve. Which amino acids are likely candidates for the unknown?

For the amino acid alanine, the major species in solution at pH 7 is the zwitterionic form, which has a negatively charged carboxylic acid group and a positively charged amino group. There is a less common neutral form in which neither group is charged.
The carboxylic acid group of alanine has a p?a of 3 The amino group of alanine has a p?a of 8
Estimate the ratio of the concentration of the neutral amino acid species to the zwitterionic species at pH 7.

. Describe the pH range of acceptable buffering behavior for the amino acids alanine, histidine, aspartic acid, and lysine.
You have 1 M (1 mol/L) solution of amino acid. This amino acid has an alpha carboxyl group with pKa = 2.0 and an alpha-
amino group with pKa = 10.0. The pH of the solution is 7.0. Calculate the concentration of the molecular form of this
amino acid that has carboxyl group protonated (COOH) and, at the same time, the amino group deprotonated (NH2).
