    Fatty acids, especially polyunsaturated, and their metabolites (eicosanoids) play many pivotal roles in human body, influencing various physiological and pathological processes. The aim of the study was to evaluate the effect of supplementation with edible oils diverse in terms of fatty acid composition on fatty acid contents, activities of converting their enzymes, and on lipoxygenase. Plant secondary metabolites can be divided into three chemically distinct groups: terpenes, phenolics, and nitro - gen-containing compounds. FIGURE A shows in sim-plified form the pathways involved in the biosynthesis of secondary metabolites and their interconnections with pri - mary metabolism. In the next three sections of this chapter.

    lipoxygenase-catalyzed arachidonic acid metabolism in normal and neoplastic mouse epidermis was assessed by cDNA cloning of the epidermal lipoxygenases and by studying their expression.   12/lipoxygenase (12/LOX) is an enzyme, which oxidizes polyunsaturated fatty acids, particularly omega-6 and -3 fatty acids, to generate a number of bioactive lipid metabolites.

Cancer and inflammation are intimately linked due to specific oxidative processes in the tumor microenvironment. Lipoxygenases are a versatile class of oxidative enzymes involved in arachidonic acid metabolism.

An increasing number of arachidonic acid metabolites is being discovered and apart from their classically recognized pro-inflammatory effects, anti-inflammatory effects are also being. Lipoxygenases are non-heme dioxygenases of polyunsaturated fatty acids. Their substrates contain a (1Z,4Z)-pentadiene system, which is oxidized to a (1S)-hydroperoxy-(2E,4Z)-pentadiene by lipoxygenases of plants and mammals and to a (1R)-hydroperoxy-(2E,4Z)-pentadiene by lipoxygenases of marine invertebrate ().All known lipoxygenases belong to the same gene family.

The essential fatty acids, linoleic acid and arachidonic acid play an important role in pancreatic cancer development and progression. These fatty acids are metabolized to eicosanoids by cyclooxygenases and lipoxygenases. Abnormal expression and activities of both cyclooxygenases and lipoxygenases have been reported in pancreatic cancer.

In this article, we aim to provide a brief. Understanding the mechanisms by which lipoxygenase and its metabolites modulate platelet function may lead to the development of a novel class of anti-platelet therapies targeting the enzyme in order to attenuate injury-induced clot formation, vessel occlusion and pathophysiological shifts in.

Abstract. Although the cyclooxygenase (COX) metabolites of arachidonic acid (AA; ; eicosatetraenoic acid) metabolism have received more attention than the metabolites of the lipoxygenases (LOX), there is growing evidence that inhibition of LOX offers an effective means of cancer (and other disease) prevention.Lipoxygenases (LOXs; EC[][1]) are nonheme iron-containing dioxygenases widely distributed in plants and animals.

LOX catalyzes the addition of molecular oxygen to polyunsaturated fatty acids containing a (Z, Z)-1,4-pentadiene system to produce an unsaturated fatty acid hydroperoxide.Lipoxygenases (EC ) are a family of (non-heme) iron-containing enzymes most of which catalyze the dioxygenation of polyunsaturated fatty acids in lipids containing a cis,cis-1,4- pentadiene into cell signaling agents that serve diverse roles as autocrine signals that regulate the function of their parent cells, paracrine signals that regulate the function of nearby cells, and.
