They may be comprised of protein or, less commonly, RNA (as ribozymes). Od. They are biological catalysts. e. They increase the amount of product at equilibrium when compared to a non-enzyme catalyzed reaction. The amino acids glutamine and glutamic acid are shown in the figure at pH 7. They differ only in the structure of their side chains. Example of an MCAT-type question: of At pH 7, glutamic acid can participate in a molecular interaction that is not possible for glutamine.
