Comparative methyl linoleate and methyl linolenate oxidation in the presence of bovine serum albumin at several lipid/protein ratios. Rapid headspace gas chromatography of hexanal as a measure of lipid peroxidation in biological samples. Biodiesel fuel is composed primarily of fatty acid methyl esters (FAMEs) produced by a transesterification reaction between a ncomponentsofbiodiesel fuel derived from a soy feedstock are found to be the following five FAMEs: methyl palmitate, methyl stearate, methyl oleate, methyl linoleate, and methyl linolenate.

    The adsorption analysis of six binary mixtures composed of ethyl stearate, ethyl oleate, ethyl linoleate, and ethyl linolenate has been studied on alumina columns. Distillation methods have been shown by other workers to fractionate the stearate-oleate system but not the oleate-linoleate system. Application of the adsorption analysis technique resulted in fractionation of all six systems.   Methyl linolenate was isolated from nearby eluting methyl oleate, methyl stearate and methyl linoleate within analysis times of 10s without measureable complications from charge suppression in the ion source or leakage in filtering of ions with close proximity of dispersion behavior.

Analysis of FAME are normally performed by using GC/MS. Analysis of FAME by ion fragmentation according to double bond was discussed in this : Eka Dian Pusfitasari, Andreas Andreas, Hendris Hendarsyah Kurniawan. Abstract. Autoxidized methyl oleate and linoleate were reduced with NaBH 4 and fractionated with a preparative high-pressure liquid chromatography (HPLC) reverse phase column.

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

Methyl linoleate is found in cloves. It is part of a mixture with methyl linolenate (*FEMA *) which is used as a flavouring ingredient.

Methyl stearate was qualitatively detected in water samples collected from Lake Pontchartrain, LA, Spring, (6). It was detected but not quantified in samples from the lower Fox River, WI, (7). Methyl stearate was also detected in trace quantities in samples from the River Lee, UK(8).

Fatty acid methyl esters (FAMEs) analysis is an important tool both for characterizing fats and oils and for determining the total fat content in foods. Fats can be extracted from a matrix using a nonpolar solvent and saponified to produce salts of the free fatty acids.Temperature (K) A B C Reference Comment; - Rose and Schrodt, Coefficents calculated by NIST from author's data.Speeds of sound were measured for methyl oleate and methyl linoleate (C15H30O2) at pressures up to MPa along isotherms ranging from ( to ) K.
