Question:

The compound levodopa C9H11NO4 (usually referred to a L-dopa) is used in the treatment of Parkinson’s disease. The chemical structure (not showing its carbon atoms and attached hydrogens) is

.  L-dopa -NH3 + COOThe following values are known for its equilibrium constants for the release of hydrogen ions: pK1 = 2.20 from the carboxylic acid group, pK2 = 8.75 from the NH+3 group, pK3 = 9.81 from the first OH group, and pK4 = 13.40 for a hydrogen ion release from the remaining OH group. Determine the charge on this amino acid as a function of pH.
