31. Conjugated linoleic acid as a supplement seems to have attracted the most attention from weight watchers and body builders. 32. Many fatty acids are unsaturated, some are polyunsaturated ( e . g ., those derived from linoleic acid ). 33. Linoleic acid , an omega-6 fatty acid, is especially prominent in safflower oil, corn oil, cottonseed oil and soybean oil.34. Polyunsaturated fatty acids, particularly arachidonic acid and linoleic acid , are primary targets for free radical and singlet oxygen oxidations. 35. About 85 % of the yellow-coloured dihydroazulene are esterified with stearic acid and about 15 % with linoleic acid . 36. But they are usually enriched with alpha-linoleic acid , or ALA, from flax, not the DHA added to the eggs. 37. Kangaroo meat has a very high concentration of conjugated linoleic acid ( CLA ) when compared with other foods. 38. Sesame oil is rich in oleic and linoleic acids , which together account for 85 % of the total fatty acids. 39. "B . proteoclasticus " has been shown to have an important role in biohydrogenation, converting linoleic acid to stearic acid. 40. In the same study, a meta-analysis of linoleic acid used in intervention clinical trials showed no evidence of cardiovascular benefit.
