(Integrates with Chapter 2 .) Calculate the concentrations of all ionic species in a \(0.25 M\) solution of histidine at \(\mathrm{pH} 2, \mathrm{pH} 6.4,\) and \(\mathrm{pH} 9.3\).

Describe the stereochemical aspects of the structure of cystine, the structure that is a disulfide-linked pair of cysteines.

Draw a simple mechanism for the reaction of a cysteine sulfhydryl group with iodoacetamide.

Write equations for the ionic dissociations of alanine, glutamate, histidine, lysine, and phenylalanine.

Absolute configurations of the amino acids are referenced to \(\mathrm{D}\) - and t-glyceraldehyde on the basis of chemical transformations that can convert the molecule of interest to either of these reference isomeric structures. In such reactions, the stereochemical consequences for the asymmetric centers must be understood for each reaction step. Propose a sequence of reactions that would demonstrate that \(L(-)\) -serine is stereochemically related to \(L(-)\) -glyceraldehyde.
