9-Hydroxyoctadecadienoic acid[edit]
9-Hydroxyoctadecadienoic acid, commonly abbreviated as 9-HODE, is a type of hydroxy fatty acid derived from the oxidation of linoleic acid. It is one of the primary products formed during the lipid peroxidation process and is often used as a biomarker for oxidative stress in biological systems.
Chemical Structure[edit]
9-HODE is a monohydroxy fatty acid with the chemical formula C__H__O_. It is characterized by the presence of a hydroxyl group at the ninth carbon of the octadecadienoic acid chain. The molecule contains two cis double bonds located at the 9th and 12th carbon positions, which are typical of linoleic acid derivatives.
Biological Role[edit]
9-HODE plays a significant role in various biological processes. It is involved in the regulation of inflammation and has been shown to modulate the activity of peroxisome proliferator-activated receptors (PPARs), which are nuclear receptors that regulate the expression of genes involved in lipid metabolism, glucose homeostasis, and cell proliferation.
Formation and Metabolism[edit]
9-HODE is formed through the enzymatic and non-enzymatic oxidation of linoleic acid. The enzymatic pathway involves the action of lipoxygenases, while the non-enzymatic pathway involves free radical-mediated oxidation. Once formed, 9-HODE can be further metabolized by various enzymes, including cytochrome P450s and alcohol dehydrogenases, to produce other bioactive lipid mediators.
Clinical Significance[edit]
Elevated levels of 9-HODE have been associated with several pathological conditions, including atherosclerosis, diabetes mellitus, and cancer. It is often used as a biomarker to assess oxidative stress and lipid peroxidation in clinical studies. The presence of 9-HODE in tissues and biological fluids can provide insights into the oxidative status of an organism and the potential risk for developing oxidative stress-related diseases.
