With 18 carbons, 34 hydrogens, and two oxygen atoms, oleic acid, a straight-chained aliphatic organic compound, is also known as cis-9-octadecenoic acid, emersol 220, glycon, and metaupon.
Oleic acid is a clear, colorless liquid with a molecular weight of 282.52, a melting point of 16.3 degrees Celsius, a boiling point of 286 degrees Celsius, and a flash point of 189 degrees Celsius.
Known also as red oil, oleic acid is used as a chemical surfactant in industrial chemical processes and in textile manufacturing, and as an emulsifier in foods and cosmetics.

 OLEIC ACID [(Z)-9-OCTADECENOIC ACID]
Fatty acids are predominantly unbranched and those with even numbers of carbon atoms between 12 and 22 carbons long react with glycerol to form lipids (fat-soluble components of living cells) in plants, animals, and microorganisms.
The saturated fatty acids have no double bonds, while oleic acid is an unsaturated fatty acid has one double bond (also described as olefinic) and polyunsaturated fatty acids like linolenic acid contain two or more double bonds.
Fatty acids are used as basic building blocks of biological membranes, for long-term energy storage (the major components of triglycerides) as well as for the precursors of eicosanoid hormones.

 Heart-Friendly Corn Oil? New High-Oleic Corn Varieties Make It Possible   (Site not responding. Last check: 2007-10-22)
Duvick says high percentages of oleic acid "give corn oil stability with regard to flavor and deterioration and have also been linked to lowering blood cholesterol levels in people." High levels of cholesterol in the blood can lead to coronary heart disease, heart attacks, and stroke.
Oleic acid's stability, which makes for longer storage and refrigerator shelf life, may also prove attractive to makers of salad dressing.
She adds that varieties have been developed that have oils with total saturated fatty acid composition as low as 6.5 percent—compared to the 13 percent found in corn oils currently available.

Oleic acid, which is found in foods such as olives, almonds, avocados and certain nuts, is also a marker on the Essential and Metabolic Fatty Acids Analysis.
Trans fatty acids are found in solid fats produced by the food oil manufacturing process called "hydrogenation." In the U.S. these fats most often wind up in partially hydrogenated vegetable oils, although they are also found naturally in the fat of grazing animals such as cows.
Essential and Metabolic Fatty Acids Analysis measures three trans isomers, as well as a wide range of omega-3, omega-6, monosaturated, and saturated fats, to reveal their metabolic status in patients and their response to dietary and supplement interventions.

The key is an ingredient of olive oil called oleic acid, they say.

Not only did oleic acid suppress activity of the gene, it also boosted the effectiveness of a breast cancer drug called herceptin, which has helped to prolong the lives of many patients.
