Where Can I Buy Oleic Acid
Oleic acid is a naturally occurring, odorless, colorless oil. Oleic acid is found in flaxseed oil, borage (a Mediterranean herb) oil, evening primrose oil, olive oil (less in virgin olive oil), pecan oil, canola oil, peanut oil, macadamia oil, sunflower oil, grape seed oil, sea buckthorn oil and sesame oil. You can also find it in animal fat. Oleic acid at appropriate levels has been implicated in cancer prevention in some (but not all studies), and reduces cholesterol levels.

The U.S. Food and Drug Administration (FDA) has determined that there is credible evidence to support a qualified health claim that consuming oleic acid in edible oils, such as olive oil, sunflower oil, or canola oil, may reduce the risk of coronary heart disease. After conducting a systematic review of the available scientific evidence, the FDA now intends to exercise enforcement discretion over the use of two qualified health claims characterizing the relationship between consumption of oleic acid in edible oils (containing at least 70% of oleic acid per serving) and reduced risk of coronary heart disease. Oleic acid is a monounsaturated fat which, when substituted for fats and oils higher in saturated fat, may reduce the risk of coronary heart disease.
Fatty acids (or their salts) often do not occur as such in biological systems. Instead fatty acids such as oleic acid occur as their esters, commonly triglycerides, which are the greasy materials in many natural oils. Oleic acid is the most common monounsaturated fatty acid in nature. It is found in fats (triglycerides), the phospholipids that make membranes, cholesterol esters, and wax esters.[6]
The biosynthesis of oleic acid involves the action of the enzyme stearoyl-CoA 9-desaturase acting on stearoyl-CoA. In effect, stearic acid is dehydrogenated to give the monounsaturated derivative, oleic acid.[6]
Oleic acid undergoes the reactions of carboxylic acids and alkenes. It is soluble in aqueous base to give soaps called oleates. Iodine adds across the double bond. Hydrogenation of the double bond yields the saturated derivative stearic acid. Oxidation at the double bond occurs slowly in air, and is known as rancidification in foodstuffs and as drying in coatings.
The trans isomer of oleic acid is called elaidic acid or trans-9-octadecenoic acid. These isomers have distinct physical properties and biochemical properties. Elaidic acid, the most abundant trans fatty acid in diet, appears to have an adverse effect on health.[16] A reaction that converts oleic acid to elaidic acid is called elaidinization.
In chemical analysis, fatty acids are separated by gas chromatography of their methyl ester derivatives. Alternatively, separation of unsaturated isomers is possible by argentation thin-layer chromatography.[17]
Oleic acid as its sodium salt is a major component of soap as an emulsifying agent. It is also used as an emollient.[50] Small amounts of oleic acid are used as an excipient in pharmaceuticals, and it is used as an emulsifying or solubilizing agent in aerosol products.[51]
Oleic acid is used to induce lung damage in certain types of animals for the purpose of testing new drugs and other means to treat lung diseases. Specifically in sheep, intravenous administration of oleic acid causes acute lung injury with corresponding pulmonary edema.[52]
Oleic acid is the topmost monounsaturated fat in the human diet.[56] Monounsaturated fat consumption has been associated with decreased low-density lipoprotein (LDL) cholesterol, and possibly with increased high-density lipoprotein (HDL) cholesterol.[57] Oleic acid may be responsible for the hypotensive (blood pressure reducing) effects of olive oil that is considered a health benefit.[58] A 2017 review found that diets enriched in oleic acid are beneficial for regulating body weight.[59]
The United States FDA has approved a health claim on reduced risk of coronary heart disease for high oleic (> 70% oleic acid) oils.[60] Some oil plants have cultivars bred to increase the amount of oleic acid in the oils. In addition to providing a health claim, the heat stability and shelf life may also be improved, but only if the increase in monounsaturated oleic acid levels correspond to a substantial reduction in polyunsaturated fatty acid (especially α-Linolenic acid) content.[61] When the saturated fat or trans fat in a fried food is replaced with a stable high oleic oil, consumers may be able to avoid certain health risks associated with consuming saturated fat and trans fat.[62][63]

Abstract. The heterogeneous processing of organic aerosols by trace oxidants has many implications to atmospheric chemistry and climate regulation. This review covers a model heterogeneous reaction system (HRS): the oleic acid-ozone HRS and other reaction systems featuring fatty acids, and their derivatives. The analysis of the commonly observed aldehyde and organic acid products of ozonolysis (azelaic acid, nonanoic acid, 9-oxononanoic acid, nonanal) is described. The relative product yields are noted and explained by the observation of secondary chemical reactions. The secondary reaction products arising from reactive Criegee intermediates are mainly peroxidic, notably secondary ozonides and α-acyloxyalkyl hydroperoxide oligomers and polymers, and their formation is in accord with solution and liquid-phase ozonolysis. These highly oxygenated products are of low volatility and hydrophilic which may enhance the ability of particles to act as cloud condensation nuclei (CCN). The kinetic description of this HRS is critically reviewed. Most kinetic studies suggest this oxidative processing is either a near surface reaction that is limited by the diffusion of ozone or a surface based reaction. Internally mixed particles and coatings represent the next stage in the progression towards more realistic proxies of tropospheric organic aerosols and a description of the products and the kinetics resulting from the ozonolysis of these proxies, which are based on fatty acids or their derivatives, is presented. Finally, the main atmospheric implications of oxidative processing of particulate containing fatty acids are presented. These implications include the extended lifetime of unsaturated species in the troposphere facilitated by the presence of solids, semi-solids or viscous phases, and an enhanced rate of ozone uptake by particulate unsaturates compared to corresponding gas-phase organics. Ozonolysis of oleic acid enhances its CCN activity, which implies that oxidatively processed particulate may contribute to indirect forcing of radiation.
An unsaturated fatty acid that is the most widely distributed and abundant fatty acid in nature. It is used commercially in the preparation of oleates and lotions, and as a pharmaceutical solvent. (Stedman, 26th ed)
Fatty acid uptake by different tissues may be mediated via passive diffusion to facilitated diffusion or a combination of both 2. Fatty acids taken up by tissues are then stored in the form of triglycerides or oxidized 2. Oleic acid was shown to penetrate rat skin 2. Following oral administration of Brucea javanica oil emulsion in rats, the time of oleic acid to reach peak plasma concentration was approximately 15.6 hours 1.
Radio-labelled oleic acid was detected in the heart, liver, lung, spleen, kidney, muscle, intestine, adrenal, blood, and lymph, and adipose, mucosal, and dental tissues 2. Oleic acid is primarily transported via the lymphatic system 2.
Like most fatty acids, oleic acid may undergo oxidation via beta-oxidation and tricarboxylic acid cycle pathways of catabolism, where an additional isomerization reaction is required for the complete catabolism of oleic acid. Via a series of elongation and desaturation steps, oleic acid may be converted into longer chain eicosatrienoic and nervonic acid 2.
A study conducted by the University of Edinburgh found that the monounsaturated fatty acid encourages the synthesis of a cell molecule (miR-7) that supports a reduction in cancer-causing proteins from developing.
These beneficial effects are due to the potential anti-inflammatory properties of oleic acid and its ability to inhibit the attenuation of the insulin signaling pathway. This could potentially suggest that the intake of oleic acid can help control the amount of insulin released to increase glucose uptake from the blood[*].
Consumption of olive oil and other foods rich in omega-9 fatty acids increases levels of oleic acid in membranes. The fatty acid alters the structure of the membrane and its physical properties and controls cell signaling, which leads to a decrease in blood pressure.
The top oleic acid foods are usually found in quality fats such as oils. While the whole version of the food is typically a source of oleic acid as well, the oils provide a higher concentration of the omega-9 fatty acid, so you get the most benefit from those. 041b061a72
