Abstract:
A test for lipase activity is provided wherein trilinolein, or an equivalent as defined herein, is employed in an emulsified form as a substrate. Reduced incubation times and improved accuracy are obtained by providing an excess of lipoxygenase to convert the linoleic acid product of lipolysis to linoleic acid hydroperoxide which is measurable with great accuracy at low concentrations by spectrophotometric or kinetic assay techniques, for example.
