Lipoxygenases (LOX) are a family of non-heme iron-containing enzymes that catalyze the dioxygenation of polyunsaturated fatty acids like arachidonic acid. This process forms hydroperoxy derivatives, such as HPETEs, which are precursors to bioactive signaling molecules like pro-inflammatory leukotrienes and anti-inflammatory lipoxins.
Reported Benefits (Provisional)
Origin & History
Lipoxygenase (LOX, EC 1.13.11.x) is a non-heme iron-containing enzyme found ubiquitously in plants, animals, and human tissues. It catalyzes the stereo- and regioselective oxidation of polyunsaturated fatty acids, notably arachidonic acid, into hydroperoxides. These hydroperoxides serve as crucial precursors for a diverse array of biologically active lipid mediators, including leukotrienes and lipoxins, which are central to inflammatory signaling and immune modulation.
Research Narrative (Provisional)
Extensive peer-reviewed research, including in vitro, animal, and human observational studies, has thoroughly documented lipoxygenase's central role in inflammatory pathways, asthma, cancer biology, and atherosclerosis. The enzyme's inhibition has become a significant therapeutic target in drug development for conditions such as asthma, inflammatory bowel disease, and various dermatologic disorders.

Nutritional Profile
- Non-heme iron-containing enzyme - Substrate specificity: Polyunsaturated fatty acids, particularly arachidonic acid, linoleic acid - Catalytic activity: Oxygenation of fatty acids to hydroperoxides
Reported Mechanism (Provisional)
Lipoxygenase enzymes catalyze the insertion of molecular oxygen into the cis,cis-1,4-pentadiene system of polyunsaturated fatty acids, including arachidonic and linoleic acid. This reaction generates hydroperoxy derivatives (e.g., hydroperoxyeicosatetraenoic acids, HPETEs). These HPETEs serve as crucial precursors for the biosynthesis of various bioactive signaling molecules, such as pro-inflammatory leukotrienes (via the 5-LOX pathway) and anti-inflammatory lipoxins, as well as 12S-hydroxyeicosatetraenoic acid (12-HETE) from the 12-LOX pathway.
Clinical Narrative (Provisional)
Extensive peer-reviewed research, encompassing in vitro, animal, and human observational studies, has robustly documented lipoxygenase's central role in inflammatory pathways. These studies have linked LOX activity to conditions such as asthma, cancer biology, and atherosclerosis. While specific sample sizes are not uniformly reported across this broad body of literature, the consistent findings underscore that the enzyme's inhibition has emerged as a significant therapeutic target in drug development for these diseases.
