Detection of Water in Lipase-Catalyzed Reactions in Reverse Micelles as Studied by Infrared Spectroscopy

The hydrolytic activity of lipolytic enzymes in reverse micelles can be measured continuously with Fourier Transform infrared spectroscopy (FTIR) by following in the region of the OH-stretching band the water consumption during the reaction. This possibility is unique to reverse micellar solutions, because they are optically transparent and because they contain only a limited amount of water.
