General description

Oleic acid (OA), a non-essential fatty acid, is classified as monounsaturated fatty acid (MUFA) richly present in olive oil. Its quantitative removal from the mixtures of triglyceride and partial glycerides has been reported. OA is widely used as a surfactant for the stabilization of magnetic nanoparticles. Monodisperse magnetite nanoparticles (7 and 19nm) coated with OA have been prepared.

Application

Oleic acid has been used:
  • to study the effects of fatty acids on gastric cancer (GC)
  • to induce lipid droplet formation in cell culture
  • as an additive in the magnetorheological fluid preparation.
Oleic acid may be used in the preparation of 10-hydroxy octadecanoic acid and methyl ester of the 10-hydroxy octadecanoic acid.

Biochem/physiol Actions

Oleic acid is known to improve immune function and health. Dietary supplement of this fatty acid contributes to the reduction in cholesterol levels, atherogenesis risk, blood pressure, and host versus graft response. Oleic acid has been proven to benefit autoimmune diseases by exhibiting anti-inflammatory action. It also ameliorates the condition of breast cancer. Oleic acid produces physiological effects such as protein kinase C activation in hepatocytes, uncoupling oxidative phosphorylation, and 2,4-dinitrophenol−stimulated ATPase inhibition. This action can be reversed by adding serum albumin.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. You describe Product O1008, Oleic acid, as a liquid in your Specification Sheet, but you do not give its concentration.

    Oleic acid is a liquid at room temperature. Its molarity, calculated from its density and molecular weight (0.89 g/mL at 25 degrees C and 282.46 g/mol, respectively) is approximately 3.15 mol/L.

  4. In what solvents can Product O1008, Oleic acid, be dissolved or diluted?

    Per the chemicals encyclopedia published by the Royal Society of Chemistry, 12th ed., Entry# 6965, oleic acid is soluble in alcohol, benzene, chloroform, ether, fixed and volatile oils, but is practically insoluble in water.

  5. How can one determine whether Product O1008, Oleic acid, has undergone oxidation?

    Sigma's oleic acid is a clear, colorless to very faint yellow viscous liquid. It is sensitive to air and light. When it becomes oxidized, it aquires a much darker yellow to brown color.

  6. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
