Oleic acid

Absorption

Fatty acid uptake by different tissues may be mediated via passive diffusion to facilitated diffusion or a combination of both . Fatty acids taken up by tissues are then stored in the form of triglycerides or oxidized . Oleic acid was shown to penetrate rat skin . 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 .

Toxicity

In rat, oral LD50 74 g/kg and intravenous LD50 is 2.4 mg/kg . Dermal LD50 in guinea pig was >3000 mg/kg .

Description

Oleic acid is a monounsaturated fatty acid and a major component of membrane phospholipids that has been found in human plasma, cell membranes, and adipose tissue. It contributes approximately 17% of the total fatty acids esterified to phosphatidylcholine, the major phospholipid class in porcine platelets. Oleic acid inhibits collagen-stimulated platelet aggregation by approximately 90% when used at a concentration of 10 μg/ml. It also inhibits fMLF-induced neutrophil aggregation and degranulation by 55 and 68%, respectively, when used at a concentration of 5 μM, similar to arachidonic acid ( | 90010.1 | 10006607). Oleic acid (60 μM) induces release of intracellular calcium in human platelets. In vivo, oleic acid increases TNF-α, IL-8, IL-6, and IL-1β production, neutrophil accumulation, and apoptotic and necrotic cell death in mouse lung and has been used to induce lung injury in a mouse model of acute respiratory distress syndrome (ARDS).

The Uses of Oleic acid

Oleic acid is a monounsaturated omega-9 fatty acid. Oleic Acid is obtained by the hydrolysis of various animal and vegetable fats and oils. Oleic Acid is used as an emulsifying or solubilizing agent i n aerosol products.

Background

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)

What are the applications of Application

Oleic Acid is an anti-proliferative agent and activator of PKC and CaMKII

Metabolism

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 .
