Abstract
Many organic reactions are catalyzed by strong acids or bases that protonate or deprotonate neutral reactants leading to reactive cations or anions that proceed to products. In enzyme reactions, only weak acids and bases are available to hydrogen bond to reactants and to transfer protons in response to developing charges. Understanding this difference goes a long way toward applying organic concepts to the mechanisms of bioorganic chemistry.

Telling It Like It Is: Teaching Mechanisms in Organic Chemistry
Addison AultJournal of Chemical Education2010 87 (9), 937-941Telling It Like It Is: Teaching Mechanisms in Organic Chemistry
Addison AultJournal of Chemical Education2010 87 (9), 937-941In this article I support and extend the ideas presented by J. Brent Friesen in his article Saying What You Mean; Teaching Mechanisms in Organic Chemistry (JCE November, 2008). I emphasize “telling the truth” about proton transfers. The truth is that in ...

Addison AultJournal of Chemical Education2008 85 (9), 1246Frank Westheimer's Early Demonstration of Enzymatic Specificity
Addison AultJournal of Chemical Education2008 85 (9), 1246In this article I review one of the most significant accomplishments of Frank H. Westheimer, one of the most respected chemists of the 20th century. This accomplishment was a series of stereospecific enzymatic oxidation and reduction experiments that led ...
