I would like to formalute the same question but in an other
The pK value for dissociation of the C(gamma) carboxyl group
of aspartic acid is 4.4. So there are two different
molecules, aspartic acid (protonated) and aspartate (deprotonated).
The question is, whether aspartic acid or aspartate is more hydrophobic.
