Common Name | 9E,11E-Octadecadienoic acid |
---|
Description | 9E,11E-Octadecadienoic acid, also known as isolinolenic acid, (e,e)-isolinoleic acid or (9E,11E)-9,11-octadecadienoate, belongs to the class of organic compounds known as lineolic acids and derivatives. These are derivatives of lineolic acid. Lineolic acid is a polyunsaturated omega-6 18 carbon long fatty acid, with two CC double bonds at the 9- and 12-positions. Conjugated linoleic acid (CLA) is an integral term for the mixture of positional and geometrical isomers of the octadecadienoic acids, whose two double-bonds are separated with one single-bond. The most common isomers are cis-9, trans-11, and trans-10, cis-12. 9E,11E-Octadecadienoic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 9E,11E-Octadecadienoic acid has been detected in milk and dairy products (from cow) and red meat. This could make 9E,11E-octadecadienoic acid a potential biomarker for the consumption of these foods. 9E,11E-Octadecadienoic acid is one of many unsaturated fatty acids that have been identified in the oil of cannabis seeds (PMID: 6991645 ). Much attention has focused on the therapeutic potential of conjugated linoleic acid. Initial animal studies associated conjugated linoleic acid with beneficial health properties, such as reducing the risk of cancer, diabetes, atherosclerosis, inflammation, and obesity. More recent human CLA-supplementation studies have often shown conflicting and less convincing health benefits. The marked variation between studies may reflect the isomer-specific effect of the individual conjugated linoleic acid isomers, which can often have opposing effects. Detrimental effects have been observed in some studies, after supplementation with the trans-10, cis-12 conjugated linoleic acid isomer. Diet composition may modulate CLA effects on body fat accumulation. Contemporary dietary recommendations tend to limit red meat and dairy products and the possible CLA deficiencies must be compensated with dietary supplements. However, with human studies, a specific dietary pattern that controls and includes CLA has not been established. As a result, differences among studies and among subjects in the same study are likely. In rodents, the effects of CLA vary with genotype, suggesting that genetic predisposition to fat accumulation can play an important role in the effectiveness of CLA. Human volunteers with different body mass index have participated in the published studies and even in the same experiment. So, differences in lipid metabolism among subjects could help to explain the discrepancies observed in the literature. Age and maturity of the participants may also impact these studies (PMID: 17053429 , 17217167 , 17554969 , 16477173 ). | Read more...
