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.

Disadvantages of Double Reciprocal Plots R. Bruce Martin
Because they involve grossly uneven weightings of points, the linear and formally similar double reciprocal Benesi-Hildebrand and Lineweaver-Burke plots should never be used to resolve equilibrium and enzyme kinetic results.

Binding energy and enzymatic catalysis Hansen, David E.; Raines, Ronald T.
The authors discuss the fundamental role that the favorable free energy of binding of the rate-determining transition state plays in catalysis and review the principle that many catalytic factors are realized by the use of this binding energy.
