Omega-3 oils fatty acids

A USDA report indicates that between 1967 and 1988, butter consumption remained stable at 2 kg per capita, margarine dropped from 5.1 to 4.7 kg, and measured total fat intake per day dropped from 84.6 to 73.3 g (14). This study also projects that the reduced consumption of tropical oils is only temporary and will return to former use levels, possibly even higher. One reason for this projected rise in tropical oil consumption is the knowledge of the beneficial effects of medium-chain length acids high in lauric oils. There is a keen interest in omega-3 fatty acids, as well as linoleic acid, contained in fish oils. 

Omega-3 fatty acids (eicosapentaenoic acid and docosa-hexaenoic acid), the predominant fatty acids in the oil of cold-water fish, lower triglycerides by as much as 35% when taken in large amounts. Fish oil supplements may be useful for patients with high triglycerides despite diet, alcohol restriction, and fibrate therapy. This effect may be modulated thru PPAR-a and a reduction in apolipoprotein B-100 secretion. Omega-3 fatty acids reduce platelet aggregation and have... 

Fish Oils (Marine-Derived Omega-3 Fatty Acids)... 

Fish oils These contain high levels of omega-3 fatty acids, which have a number of properties that could explain why hsh oils or a diet high in oily hsh have a protective effect ... 

The major omega-3 fatty acid in hsh oil is eicosapentae-noic acid, which contains hve double bonds compared with only four present in the omega-6 fatty acid, arachidonic acid. When eicosapentaenoic acid is substrate for eico-sanoid production, it gives rise to prostacyclins and thromboxanes of the three series (Figure 22.9(a)) whereas when arachidonic acid is substrate, it gives rise to the two series, thromboxane A2 and prostacyclin I2. Thromboxane A3 has...

The psychiatric community, the lay press, and ads on the Internet have drawn attention to the role of essential fatty acids (EFAs) on neural development and on the treatment of mental illness. The EFAs are often referred to as omega-3 and omega-6 fatty acids, and include fish oil, flax seed oil, and evening primrose oil supplements. 

SCCO2 fractionation of fish oil ethyl esters was employed to prepare ethyl esters of two omega-3 fatty acids. The triacylglycerol products were isolated using supercritical fluid fractionation (Nilsson et al., 1989). 

The effect of dietary fats on hypertriglyceridemia is dependent on the disposition of double bonds in the fatty acids. Omega-3 fatty acids found in fish oils, but not those from plant sources, activate peroxisome proliferator-activated receptor-alpha (PPAR- ) and can induce profound reduction of triglycerides in some patients. They also have antiinflammatory and antiarrhythmic activities. In contrast, the omega-6 fatty acids present in vegetable oils may cause triglycerides to increase. 

Oily fish and extracted fish oils contain high concentrations of EPA and DHA. Fish oils also contain vitamins A and D. Oil derived from cod, halibut, or shark liver, or from fish body, typically contains about 200 mg/ml of long-chain omega-3 fatty acids. In addition, cod liver oil provides 50 pg/ml of vitamin A and 2 pg/ml of vitamin D. Many fish oil supplements are artificially enriched with omega-3 fatty acids.
