Descrição

Descrição geral

Methyl linoleate is a methyl ester of the tri-unsaturated essential fatty acid, linoleic acid.

Methyl linoleate, non-conjugated, is more easily oxidized than conjugated methyl linoleate .

Aplicação

The oxidation of methyl linoleate in organic solution and phosphatidylcholine (PC) in liposomal membranes induced by an azo initiator has often been used as a model for lipid peroxidation in vivo .

This analytical standard can also be used as follows:

• Comparative analysis of gas chromatography-combustion-mass spectrometry and gas chromatography-flame ionization detector methods for the determination of fatty acid methyl esters (FAMEs) in biodiesel samples
• Gas chromatography-tandem differential mobility spectrometry (DMS) based separation and quantification of 16 methyl- and ethyl- fatty acid esters from biodiesel samples
• Simultaneous determination of fatty acid methyl esters in commercial food oil samples by gas chromatography-vacuum ultraviolet (GC-VUV) spectroscopy
• Measurement of fatty acid methyl ester composition of various edible oil samples by 1H nuclear magnetic resonance (1H NMR) spectroscopy combined with partial least squares (PLS) method
• Analysis of coffee oil and residue obtained from roasted coffee beans to determine the composition of 11 fatty acids following their methyl esterification by gas chromatography coupled with a flame ionization detector (GC-FID)
• Simultaneous determination of fatty acids in bovine colostrum samples by GC-FID after their derivatization to ester forms using an acidic catalyst boron trifluoride
