Common Name | 9,10-Epoxyoctadecenoic acid |
---|
Description | 9,10-Epoxyoctadecenoic acid (9,10-EOA) is a peroxidation product of linoleic acid (LA). 9,10-EOA is a naturally occurring component of oxidized low density lipoprotein (LDL), the level of which increases with aging, atherosclerosis, and rheumatoid arthritis, perhaps due to an increase in 15-lipoxygenase and free oxygen radicals. 9,10-EOA is a proliferator-activated receptors (PPAR) gamma2 ligand, that is antiosteogenic without stimulating adipocyte differentiation. Studies in dogs suggest that 9,10-EOA has toxic cardiovascular effects. (PMID: 12665667 , 12021203 , 10667371 ). |
