[The lipase/lipoxygenase bienzyme system in AOT reversed micelles in octane]

In this work it is shown that the bienzyme lipase/lipoxygenase system can function in reversed micelles of bis(2-ethyl)hexyl sulfosuccinate (AOT) in octane. As a lipase substrate, a fish fat preparation (fat of sea mammals) with a high content of polyunsaturated fatty acids was used. It was demonstrated that the bienzyme reaction proceeded in a stationary mode and had a rate-limiting step catalyzed by lipase. Under optimal conditions, the efficacy of functioning of the bienzyme system was by an order of magnitude higher than that in water. The lipase/lipoxygenase bienzyme system can be used as a new method of spectrophotometric determination of lipase activity. The English version of the paper.
