LIQUID MEMBRANE-TRANSPORT USING BORONIC ACID CARRIERS

This review summarizes the recent research on a new application with b oronic acids, namely their ability to act as transport carriers in bul k, liquid organic membranes. To date, boronic acids have been shown to facilitate the transport of reducing monosaccharides, ribonucleosides , aryl glycosides, catecholamines, cy-amino acids, and riboflavin. The transport can either be passive (down a solute concentration gradient ) or active (against a solute concentration gradient). The various che mical mechanisms for boronic acid mediated transport are described, as well as the chemical and physical Factors that control transport rate s.
