CH3(CH2)7CH:CH(CH2)7COOH A transisomer of an unsaturated fatty acid, oleic acid; crystallizes as colorless leaflets, melts at 44°C, boils at 288°C (100 mmHg), insoluble in water, soluble in alcohol and ether; used in chromatography as a reference standard.

Plasma phospholipid elaidic acid concentrations, the main TFA isomer occurring during partial hydrogenation of vegetable oils found in a myriad of industrial foods, were positively associated with the intake of highly processed foods within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort [44,45].

Template formations with other C18 fatty acids are also tested, namely, oleic acid (cis-9-octadecenoic acid) and elaidic acid (trans-9-octadecenoic acid).
"Coupling to elaidic acid improves the bioavailability of the agent without impeding its epigenetic effect," explained project leader Frank Lyko.
Schaefer (2002) reported that the presence in the diet of elaidic acid, which contains trans double bonds, is associated with increased low-density lipoprotein (LDL) levels and decreased high-density lipoprotein (HDL) levels.
Plasma lipoprotein lipid and Lp (a) changes with substitution of elaidic acid for oleic acid in the diet.
(B) Comparison with an authentic sample of the isomeric elaidic acid supports this assignment.
However, in plasma samples, the retention time of the TBDMS ester of oleic acid was very similar to that of its trans isomer, elaidic acid. This would interfere with tracer measurements because we administer the [[1.-sup.13]C]-labeled cis isomer (oleic acid).

These are oleic acid (cis 18:1[Delta]9) and elaidic acid (trans 18:1[Delta]9).
Another TFA, elaidic acid, could influence arachidonic acid metabolism, playing an important role in formation of athermanous plaque [6].
