Twenty-two genotypes of Brassica (B. rapa, B. juncea, and B. napus) were studied for correlation co-efficient between major fatty acids and path coefficient analysis to partition the cause and effect relationship into direct and indirect components. Correlation coefficient of major fatty acids revealed that significant and positive correlation was between palmitic and oleic acids, palmitic and ...
Delta 6-desaturase actiyity and fatty acid composition of liyer microsomes were measured periodically in rats fed diets high in oc-linolenic acid (perilla oil) containing either casei" (CAS) or soybean protein (SOY) as a protein source. Delta 6-desaturase activity measured by using li"oleic'acid as a substrate (18:2n-6.18:3n-6) and the linoleic acid desaturation index as estimated by the (20:3+...
Inflammation plays an important role in health and disease. Most of the chronic diseases of modern society, including cancer, diabetes, heart disease, arthritis, Alzheimer's disease, etc. have inflammatory component. At the same time, the link between diet and disease is also being recognized. Amongst dietary constituents, fat has gained most recognition in affecting health. Saturated and trans...
The changes in lipid and fatty acid contents after soaking, cooking, germination and fermentation of three white sorghum varieties were studied to improve cereal quality. The results revealed that oil in raw sorghum varieties ranged from 3.58 to 3.91%, respectively and ‘Dorado’ represents the highest variety in oil content. As general trend after germination, oil content was decreased. Fatty ac...
Supplementary dietary plant oils have the potential to alter milk fatty acid composition in ruminants as a result of changes in the amount and kind of fatty acid precursors. We hypothesized that linseed oil in combination with malate (a key propionate precursor in the rumen) would increase ∆9 unsaturated fatty acids and specific gene expression in somatic cells and mammary glands of lactating g...
The fixed oil of L. usitatissimum (flaxseed/linseed) inhibited PGE2-, leukotriene-, histamine- and bradykinin-induced inflammation. The oil also inhibited arachidonic acid-induced inflammation, suggesting its capacity to inhibit both cyclooxygenase and lipoxygenase pathways of arachidonate metabolism. In tail immersion model, the oil raised the pain threshold to a lesser extent than morphine bu...
The artificial gene D6D encoding the enzyme ∆⁶desaturase was designed and synthesized using the sequence of the same gene from the fungus Thamnidium elegans. The original start codon was replaced by the signal sequence derived from the wheat gene for high-molecular-weight glutenin subunit and the codon usage was completely changed for optimal expression in wheat. Synthesized artificial D6D gene...
Omega-3 fatty acids have potential antiatherogenic, antithrombotic, and antiarrhythmic properties, but their role in coronary heart disease remains controversial. To evaluate the association of omega-3 fatty acids in adipose tissue with the risk of myocardial infarction in men, a case-control study was conducted in eight European countries and Israel. Cases (n=639) included patients with a firs...
Plants respond to chilling exposure by increasing the relative proportion of polyunsaturated fatty acids in their lipids. However, unlike the response in many other organisms, plant fatty acid desaturase genes are typically not upregulated during this process. We expressed the Brassica napus FAD3 gene, which encodes an enzyme for synthesis of linolenic acid, in Saccharomyces cerevisiae and obse...
