Omega-9 oils properties

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 ... 

A study is presented of the synthesis and properties of the novel synthetic zeolite omega. The synthesis variables and kinetics of formation are discussed, as well as the ion exchange, sorption, and thermal properties. By decomposition of imbibed tetra-methylammonium ions and exhaustive treatments of the zeolite with ammonium ions, a pure hydrogen form can be obtained which is a suitable substrate for the preparation of hydrocarbon conversion catalysts. Several catalysts were prepared and utilized to isomerize n-hexane, and to hydrocrack a heavy gas oil. 

Fatty acid composition of regular flax oil is different from other commercial oils because of the very high contribution of ALA, usually above 50% (Table 2). Because of the high content of this unique fatty acid, flaxseed and flax oil are often used as food supplements, where enrichment with omega-3 fatty acids is needed. This fatty acid is susceptible to oxidation it oxidizes 20 0 times faster than oleic acid and 2 times faster than linoleic acid (8). This property makes the oil a good material for paint and plastic production where fast oxidation is required. Flax oil contains low amounts of saturated fatty acids (SFA) compared with low linolenic flax oil (Linola), soybean, and sunflower oils however, it is higher than canola oil (Table 2). Canola oil contains the lowest amount of SFA among all commercial oils. 

Refined camelina oil was blended into fat phase to produce margarines and spreads enriched in omega-3 fatty acids. The resulting spreads had physical properties similar to a product based on typical commercial oils. The stability of the new product was satisfactory, and off-flavors were not detected after 6 months of storage (76). 

The nicotinic acid group (acipimox, nicotinic add) can lower cholesterol and triglyceride levels by an action on enzymes in the liver. The fish oils (e.g. omega-3 marine triglycerides) are dietary supplements that may be useful in treating hypertriglyceridaemia. Probucoi can decrease both LDL-cholesterol and HDL-cholesterol, as well as having other beneflcial properties.

Due to a growing interest in the bioactive properties of n-3 LC-PUFAs, there is an increasing demand for purified concentrates for use as dietary supplements and in functional foods however, it is believed that traditional sources will be insufficient in meeting this demand (Bajpai and Bajpai, 1993 Lewis et al, 1999). In addition to development of improved methods of omega-3 extraction from fish oils, a possible solution is the use of alternative. 

Besides lowering plasma lipids and the apparent protection in thrombosis, dietary supplements enriched in omega-3 fatty acids have proved to lower blood pressure, alter lipoprotein metabolism and dampen platelet aggregation among other beneficial effects in humans. The two components of fish oil attracting the most attention, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are still often referred to as omega-3, or n-3 fatty acids without any further distinction. Nearly all studies that have been conducted have used a mixture of EPA and DHA. It has, however, been reported that DHA are retroconverted to EPA in cultured hepatocytes," rat and man and it is, therefore, conceivable that EPA and DHA possess different metabolic properties. ...

Chapter 8, Chemical Reactions, looks at the interaction of atoms and molecnles in chemical reactions. Chemical equations are balanced and organized into combination, decomposition, single replacement, double replacement, and combnstion reactions. Section 8.4, Functional Gronps and Reactions of Organic Componnds, and Section 8.5, Biochemical Compounds, are now Extended Topics, which classify compounds according to their strnctures to predict their properties and reactions. The Chemistry Link to Health featnres, Amines in Health and Medicine and Omega-3 Fatty Acids in Fish Oils, ... 

The combination of high oleic acid and low Unoleic add, with the conventionally low-saturated fatty acid content, is the key to the very measurable benefits of the Omega-9 oils for the food industry, that is, improved oxidative stability resulting in longer shelf life, and longer fry life, as well as clean and bland taste profile. Table 5.6 shows some physical and chemical properties of these oils. 

One explanation is that majority of omega-6 PUFA from com oil is used for energy, and is not used to produce thrombi and atheromas, whieh are required for cardiovascular disease development. Moreover, high levels of vitamin E (majorly y-tocopherol) (Elmadfa and Park, 1999) and plant sterols (0.77% by weight) (Ostlimd, et al., 2002) may counter the bad effects of omega-6 PUFA of com oil. For example, y-toeopherol, the major form of vitamin E in the eom oil, and its metabolite have more anti-inflammatory properties than a-tocopherol, the predominant form of vitamin E in the tissues and most supplements (Jiang and Ames, 2003).
