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.

Determination of the Enantiomeric Purity of Commercial L-[U-14C] Valine: An Experiment Utilizing Reversed-Phase Thin-Layer Chromatography and Liquid Scintillation Counting  Joseph W. LeFevre
The enantiomeric purity of commercial L-[U-14C]valine was determined. The process involved sequential dilution with nonradioactive DL-valine, N-dansylation using dansyl chloride, and resolution using reversed-phase thin-layer chromatography in the presence of b-cyclodextrin, a chiral mobile phase additive.

Novel method for presenting the amino acids in an introductory biochemistry course  Kuehl, LeRoy
An approach to presenting amino acids is described and is assessed as quite effective in stimulating the students' interest in a topic which they usually find quite tedious.
