Lipoxidase

 

an enzyme of the oxydoreductase class that oxidizes unsaturated fatty acids to peroxides.

Lipoxidase was first discovered in 1934 in soybeans. It was later found to exist in the seeds of other plants and in the muscle tissue of fish and mammals. The principal substrates for lipoxygenase are linoleic, linolenic, and arachidonic acids and their respective esters. Lipoxidase is activated by polypeptides.

Linoleic acid hydroperoxide (LHP), arachidonic acid hydroperoxide (AHP), and docosahexaenoic acid hydroperoxide (DHP) were prepared from linoleic acid, arachidonic acid, and docosahexaenoic acid, respectively, by means of lipoxidase. ROS membranes were peroxidized using an ascorbate-[Fe.sup.+2] experimental system.
Wheat germ contains high amounts of unsaturated fatty acid and enzymes especially lipase and lipoxidase which increased acidity during storage.
