[Measuring and investigation of omega 3 and 6 fatty acids in species of linum ssp.]

Linolenic acid [omega 3] and linoleic acid [omega 6] are essential fatty acids that our body cannot synthesis them, so these fatty acids should be taken via foods. The aim of this study was measuring of omega 3 and omega 6 fatty acids in species of linum ssp. Seed samples of linum ssp. including: L.usitatissimum L., L. strictum L., L. mucronatum Bertol, L. nodiflorum L., L. bienne Mill and L. austriacum L. were selected from Agricultural source researches center of West Azarbaijan and grown in its research farm. Oil content was measured using Leiboritz method in three replications. The amounts of fatty acids were detected and measured by gas chromatography. This study indicated; all of investigated Linum species except one species, had more amounts of omega 3 fatty acids content than other oilseeds and all of the wild Linum species had more amounts of omega 6 fatty acids content in comparison with crop species. Oil of the crop Linum had better quality and quantity than oil of the other oil seeds, also these wild species were suitable cases for biotechnological projects and elevate amounts of omega 6 essential fatty acids of crop species

Fatty acid and cholesterol in eggs: a review.

Elevated serum cholesterol, a major cause of vascular disease, has been strongly correlated with eating greater than normal amounts of cholesterol and saturated fatty acids. The role at omega-3 polyunsaturated fatty acids (PUFA), especially eicosa pentanoic acid (EPA) and decosahexaconic (DHA), has been associated with the prevention of degenerative disease. Breast milk and eggs fulfill the human requirement for DHA, however the DHA level is influenced by lactation levels and the maternal diet. Omega-3 PUFA are derived mainly from fish, eggs, and certain plants. Epidemiological observations, population studies, and basic research indicate the importance of these fatty acids for the membranes of the brain, for the retina in developing infants, and for the possibility of controlling coronary heart disease and other diseases by the ingestion of these fatty acids. Linolenic acid (LNA) enriched eggs may be an excellent source of dietary omega-3 PUFA and an ideal food ingredient for developing infants.
