Lipoxygenase is an enzyme with properties that oxidize unsaturated fatty acids, especially linoleic acid. The reaction catalyzed by lipoxygenase produces lipid hydroperoxides. This enzyme plays a key role in many biological processes, including lipid metabolism and plant defense responses.
In the baking industry, lipoxygenase is used for its ability to oxidize unsaturated fatty acids present in flour, which affects the quality of dough and finished baked goods.
