Elaidic acid is the 9-trans isomer of oleic acid. It is a monounsaturated trans-fatty acid, which can be found in partially hydrogenated cooking oils. It was revealed, that elaidic acid inhibits HHT and HETE formation in human platelets incubated with arachidonic acid. Also was shown, that trans oleic acid increased plasma CETP activity, which increases low-density lipoprotein (LDL) cholesterol and decreases high-density lipoprotein (HDL).

CNS Activity

Curator's Comment: It was demonstrated that the 18 carbon-monocarboxylic fatty acids, linoleic acid with two cis-double bonds entered brain, whereas oleic acid, with one cis-double bond, did not enter brain. It was concluded the entry of essential fatty acids into brain is accomplished in a highly selective and discrete manner

Originator

Curator's Comment: Oleic acid was recognized in pork fat by Chevreul M.E. in 1823 while the structure was elucidated later by the works of Baruch J. (1894) and Edmed F.G. (1898); it was synthesized for the first time by Noller C.R. et al. in 1934.
