Lipidomics of oxidized polyunsaturated fatty acids
Lipid mediators are produced from the oxidation of polyunsaturated fatty acids through enzymatic and free radical-mediated reactions. When subject to oxygenation via cyclooxygenases, lipoxygenases, and cytochrome P450 monooxygenases, polyunsaturated fatty acids give rise to an array of metabolites including eicosanoids, docosanoids, and octadecanoids. These potent bioactive lipids are involved ...
متن کاملFunctional lipidomics of oxidized products from polyunsaturated fatty acids.
Because of their high degree of unsaturation, polyunsaturated fatty acids (PUFA) in mammals, with mainly 18, 20 and 22 carbons, can easily be autooxidized, and converted into many oxidized derivatives and degradation products. This short review reports on some of those relevant to the evaluation of oxidative stress in situ. In addition, the enzyme-dependent oxygenation by both dioxygenases and ...
متن کاملConsequences of Essential Fatty Acids
Essential fatty acids (EFA) are nutrients that form an amazingly large array of bioactive mediators that act on a large family of selective receptors. Nearly every cell and tissue in the human body expresses at least one of these receptors, allowing EFA-based signaling to influence nearly every aspect of human physiology. In this way, the health consequences of specific gene-environment interac...
متن کاملMetabolism of Essential Fatty Acids
The fat deficiency disease in the rat (I), dog (2), and chick (3) is characterized in part by sharply increased concentrations of one or more trienoic acids in the tissues, as indicated by alkali isomerization analyses. Indeed, the increase in conjugatable triene in the mitochondrial fatty acids may be the first noticeable symptom of the onset of fat deficiency (4). The major triene component o...
متن کاملHigh sensitivity quantitative lipidomics analysis of fatty acids in biological samples by gas chromatography-mass spectrometry.
Historically considered to be simple membrane components serving as structural elements and energy storing entities, fatty acids are now increasingly recognized as potent signaling molecules involved in many metabolic processes. Quantitative determination of fatty acids and exploration of fatty acid profiles have become common place in lipid analysis. We present here a reliable and sensitive me...
