Phosphorus-based fatty acid methyl esters

Chemistry and Physics of Lipids, 2013
With the aim of designing novel transformable fatty acid diesters, various strategies for introducing phosphorus arms to the fatty backbone have been examined. While lithiated phosphine reacts classically to brominated fatty esters to afford the mono-addition product, the synthesis of phosphorylated diesters was found to be difficult, a fact related to

Determination of fatty acid methyl esters

Analytica Chimica Acta, 1985
Abstract Fatty acid methyl esters made by transesterification of extracted plasma lipids with methanolic hydrochloric acid were found to contain substances which interfered with quantitation by gas-liquid chromatography. A method to eliminate most interfering materials and a procedure that allows reproducible wetting of an inert support with acid ...

Pseudo catalytic transformation of volatile fatty acids into fatty acid methyl esters

Bioresource Technology, 2016
Instead of anaerobic digestion of biodegradable wastes for producing methane, this work introduced the transformation of acidogenesis products (VFAs) into fatty acid methyl esters (FAMEs) to validate the feasible production of short-chained fatty alcohols via hydrogenation of FAMEs.

Fatty acids, methyl esters and insect growth

Comparative Biochemistry and Physiology, 1968
Abstract 1. 1. A physiological role for fatty acids and their methyl esters in the control of growth and development of insects is discussed, and a critical review of recent work pertaining to this topic is presented. 2. 2. New data are presented to show that the inhibiting effect of methyl palmitate and lauric acid depends on the time at ...

Ester formation during fatty acid methyl esters oxidation

Journal of the American Oil Chemists' Society
AbstractThe oxidation processes of unsaturated fatty acid methyl esters (FAMEs) and vegetable oils with molecular oxygen, proceeding through a radical mechanism, lead to the formation of a wide range of compounds. The primary oxidation products, hydroperoxides, undergo further decomposition to form products with a lower molecular weight or participate ...

Catalytic hydrogenation of fatty acid methyl esters

Russian Journal of Applied Chemistry, 2012
Catalytic hydrogenation of a mixture of fatty acid methyl esters, which are produced by re-esterification of vegetable (sunflower) oil and are contained in biodiesel fuel, was studied.

The anticlastogenic potential of fatty acid methyl esters

Mutation Research/Genetic Toxicology, 1986
To test for possible anticlastogenic effects of fatty acids, the methyl esters of fatty acids--short-chain to long-chain--were examined on busulfan in Chinese hamster bone-marrow cells using the chromosome aberration test. When the experimental animals were treated with fatty acid esters and the mutagen, the chromosome-breaking actions of busulfan were

A fatty acid methyl ester (FAMES) analyzer

Journal of High Resolution Chromatography, 1989
AbstractFatty acids, as their methyl esters (FAMES), are routinely analyzed from a wide variety of plant and animal tissues and fluids. Samples have mainly been analyzed to date using capillary GC with FID detection. However, FID detection is non‐specific, and open to misinterpretation.

Gas chromatographic analysis of fatty acid methyl esters

Journal of Chromatography B: Biomedical Sciences and Applications, 1995
The full process of fatty acid methyl ester (FAME) analysis consists of esterification of lipids, and of injection, separation, identification and quantitation of the FAMEs. In order for the required accuracy and precision to be attained, each of these steps has to be optimized. Esterification of lipids can be carried out with several reagents based on

Performance of sulfoxylated fatty acid methyl esters

Journal of Surfactants and Detergents, 1999
AbstractSulfoxidation of fatty acid methyl esters with SO2, O2, and ultraviolet light of appropriate wavelength has led to the synthesis of methyl esters sulfonates or sulfoxylates known as Φ‐MES because of the possible random position of SO3 group in the alkyl chain.
