Production of Chemoenzymatic Catalyzed Monoepoxide Biolubricant: Optimization and Physicochemical Characteristics

BioMed Research International, Volume 2012, Issue 1, 2012., 2012
Linoleic acid (LA) is converted to per‐carboxylic acid catalyzed by an immobilized lipase from Candida antarctica (Novozym 435). This per‐carboxylic acid is only intermediate and epoxidized itself in good yields and almost without consecutive reactions.

Influence of the operating conditions on lipase-catalysed synthesis of ricinoleic acid estolides in solvent-free systems [PDF]

, 2008
In this work, the synthesis of ricinoleic acid estolides, also named polyricinoleic acid (PR), in two different solvent-free reaction systems, catalysed by immobilised Candida rugosa lipase is described. First, the esterification was performed in an open

15th International Sunflower Conference Synthesis of new derivatives from vegetable sunflower oil methyl esters via epoxydation and oxirane opening

Oléagineux, Corps gras, Lipides, 2001
Recently, epoxides have received increased attention because they are of interest both as end-products and as chemical intermediates; epoxidized oils, mainly High Oleic Sunflower Oil, and their ester derivatives have thus found important applications as ...

Characterization of novel Triacylglycerol Estolides from the seed oil of Mallotus philippensis and Trewia nudiflora

, 2012
Triacylglycerol estolides have been reported as components of the seed oil of a number of plant species and are generally associated with the presence of fatty acids containing hydroxyl groups. We have used MALDI-TOF MS to examine the intact acylglycerol

Rapid identification of triacylglycerol-estolides in plant and fungal oils

, 2012
Triacylglycerol-estolides are components of the storage oil of certain plant and fungal species and are generally associated with the presence of fatty acids containing hydroxyl groups.

Synthesis and Characterisation of Dihydroxystearic Acid-Estolides from Palm-Based Dihydroxystearic Acid [PDF]

, 2006
Estolide is a polyfunctional oligomer that contains ester linkages on the alkyl backbone of the molecule, which is formed by the esterification reaction between fatty acids. These ester linkages are more resistant to hydrolysis than those of triglyceride.

Plant-Based Oils for Sustainable Lubrication Solutions—Review

Lubricants
Traditional lubricants, often containing harmful chemicals and synthetic or fossil-derived oils, pose environmental risks by damaging ecosystems and threatening human health and wildlife. There is a growing demand for environmentally sustainable and cost-

Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

Journal of the American Oil Chemists' Society, Volume 103, Issue 11, Page 1373-1383, November 2026.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

Acute exercise‐induced lipolysis and increase in levels of fatty acid esters of hydroxy fatty acids in adipose tissue are impaired in obese and aged mice

Experimental Physiology, Volume 111, Issue 10, Page 4457-4497, 1 October 2026.
Abstract Improving adipose tissue (AT) metabolism through exercise might increase production of lipokines from the fatty acid esters of hydroxy fatty acids (FAHFA) family. Although exercise training can increase insulin sensitivity and levels of specific FAHFA in AT and the circulation in humans, the effects of acute exercise on FAHFA levels remain ...

Critical Contribution of Mesoporosity to the Stability of Zeolitic Catalysts for Oleate Isomerization in Continuous Flow Reactor

ChemCatChem, Volume 17, Issue 6, March 17, 2025.
Hierarchical micro‐mesoporous ferrierite and faujasite present different kinds of mesoporosity. Selectivity and stability of these zeolite catalysts depend on peculiar structural features. The shape selectivity in ferrierite micropores favors the skeletal isomerization of fatty esters and improves the cold flow properties of biodiesel. The stability of
