The Monosodium Glutamate Story: The Commercial Production of MSG and Other Amino Acids Addison Ault
Examples of the industrial synthesis of pure amino acids are presented. The emphasis is on the synthesis of (S)-glutamic acid and, to a lesser extent, (S)-lysine and (R,S)-methionine. These amino acids account for about 90% of the total world production of amino acids.

The pH at the First Equivalence Point in the Titration of a Diprotic Acid Addison Ault
I read with interest the paper entitled Easy Derivation of pH (pKa1 + pKa2)/2 Using Autoprotolysis of HA: Doubtful Value of the Supposedly More Rigorous Equation. I believe the validity of this simple result can be seen even more easily than this paper indicates.

Do pH in Your Head Addison Ault
Every aqueous solution has a pH. Two factors determine this pH: the acidic or basic strength of the solute, and its concentration. When you use pKa values to express acidic and basic strength you can easily estimate the approximate pH of many aqueous solutions of acids, bases, and their salts and their buffers.
