      The technological utility of enzymes can be enhanced greatly by using them in organic solvents rather than their natural aqueous reaction media. Studies over .   Ionic liquids (ILs) have now been acknowledged as reaction media for biotransformations. The first three examples were reported in this field in , and since then, numerous applications have been reported for biocatalytic reactions using ILs. Two topics using ILs for enzymatic reactions have been reviewed from the standpoint of biocatalyst mediating organic synthesis; the first is.

    Organic reactions are usually conducted in organic solvents, since many organic molecules react with water, and the reagents and products are usually not soluble in water. In a manner analogous to using an enzyme as a heterogeneous catalyst in nonpolar solvent, Sharpless is pioneering a technique to conduct organic reactions in water. Therefore, reaction medium engineering is an essential task in biocatalytic process development to compromise enzyme activity/stability with high substrate loads. To overcome the drawback of using water as solvent, enzymatic reactions have been performed in non-conventional reaction media (e.g. organic solvents, ionic liquids, supercritical.

Reductions with poorly water-soluble ketones were carried out at substrate concentrations of > 10 mM, and alcohols were formed with good conversions in high enantioselectivity. This comprehensive three-volume set is the standard reference in the field of organic synthesis, catalysis and biocatalysis.

Edited by a highly experienced and highly knowledgeable team with a tremendous amount of experience in this field and its applications, this edition retains the successful concept of past editions, while the contents are very much focused on new developments in the field.

Many non-aqueous enzymatic reactions have been optimized, but the book focuses primarily on work with lipases. Of the ten protocol chapters discussing reactions in organic media, seven either exclusively cover or otherwise include lipase-catalyzed reactions.

Organic Chemistry of Enzyme-Catalyzed Reactions, Revised Edition: Medicine & Health Science Books @ iews: 4. Enzymatic reactions in organic media are actually divided into two systems: reactions performed in organic solvent systems and in solvent-free systems.

The solvent-free system, i.e. the reaction mixture comprising only liquid organic substrates (such as liquid oil) without any organic solvent, if it is possible, has high volumetric performance.
