I1T HAS BEEN suggested that polyunsaturated fatty acids control, by some mechanism, the levels of blood cholesterol and other blood lipids.1 S Sinclair suggested4 that dietary deficiency of essential fatty acids is responsible for human atherosclerosis. He proposed t-hat the mechanism of atherogenesis involves a replacement of the polyunsaturated fatty acids in serum cholesterol esters by satur...

the aim of this work was to analyze the fatty acid profile in persian gulf shrimp, metapenaeus affinis that is one of the edible and well-known shrimps and has suitable amount of fatty acids specific polyunsaturated fatty acids (pufa). it has been reported that, a high dietary consumption of marine n-3 fatty acids may prevent the development of atherosclerosis and thrombosis. the fatty acids pr...

Polyunsaturated fatty acids play an important part in the structure and function of cellular membranes and are precursors of lipid mediators which play a key role in cardiovascular and inflammatory diseases. Dietary sources of essential fatty acids are vegetable oils for either linoleic or alpha-linolenic acids, and sea fish oils for eicosapentaenoic and docosahexaenoic acids. Because of the sp...

Changes in fatty acid patterns may explain many of the observed abnormalities found in obstructive jaundice. This study looked at fatty acids in plasma cholesterol esters, in a group of patients with obstructive jaundice and a matched group of controls. Significant abnormalities were demonstrated, most importantly a fall in essential fatty acids, in the jaundiced group. Overall the saturation o...

Background Background: The fatty acid composition of the sperm membrane changes drastically during spermatogenesis and may be key to its function. Previous data has shown that intake of long chain poly-unsaturated fatty acids can change the fatty acid composition of tissues, including testes and sperm. However, whether these changes in composition translate into changes in semen quality or male...

Soybeans are very versatile, both as a food product and an ingredient in many industrial products. The oil produced by soybeans is contained within many foods we eat every day. Natural soybean oil contains several essential fatty acids that our body needs to work prop‐ erly, including linoleic and linolenic acids. However, much of the soybean oil consumed in many parts of the world has been par...

Highly unsaturated fatty acids are essential components of cellular membranes of vertebrates and can modulate physiological processes, including membrane transport, receptor function and enzymatic activities. In gilthead sea bream, dietary deficiencies of essential fatty acids of marine fish raise the basal cortisol levels and alter the pattern of cortisol release after stress. The aim of the p...

Transgenic mice (named "Omega mice") were engineered to carry both optimized fat-1 and fat-2 genes from the roundworm Caenorhabditis elegans and are capable of producing essential omega-6 and omega-3 fatty acids from saturated fats or carbohydrates. When maintained on a high-saturated fat diet lacking essential fatty acids or a high-carbohydrate, no-fat diet, the Omega mice exhibit high tissue ...

Polyunsaturated fatty acids (PuFAs, lA and AlA) are not synthesized in mammals in the absence of their essential fatty acid precursors. however, hibernating animals and animals sleeping through the winter need sufficiently high amounts of these acids. The eurasian badger does not hibernate, but sleeps over winter. In the autumn the body weight of adult badgers increases even twofold, since they...
