Characterization of Triacylglycerol Estolide Isomers Using High-Resolution Tandem Mass Spectrometry With Nanoelectrospray Ionization [PDF]
Biomolecules, 2023 Triacylglycerol estolides (TG-EST) are biologically active lipids extensively studied for their anti-inflammatory and anti-diabetic properties. In this work, eight standards of TG-EST were synthesized and systematically investigated by nanoelectrospray ...

Estolides synthesis catalyzed by immobilized lipases. [PDF]
Enzyme Res, 2011 Estolides are vegetable-oil-based lubricants obtained from oleic acid or any source of hydroxy fatty acids. In this work, the estolides synthesis from oleic acid and methyl ricinoleate (biodiesel from castor oil), using immobilized commercial lipases (Novozym 435, Lipozyme RM-IM, and Lipozyme TL-IM) in a solvent-free medium was investigated. Acid value

Chemistry and physical properties of estolides
Grasas y Aceites, 2011 Estolides are a developing class of natural and synthetic compounds that have been synthesized from hydroxy oils like castor and lesquerella or by the condensation of fatty acids across the olefin of a second fatty acid.

Enzymatic biosynthesis of ricinoleic acid estolides [PDF]
Biochemical Engineering Journal, 2005 Candida rugosa lipase has been shown to have sufficient activity to catalyse the enzymatic synthesis of ricinoleic acid estolides in a batch reactor. The water requirements of the reactor change during the reaction: at the beginning of the process a minimum amount of water is necessary but, later, the reaction mixture must be dried out to obtain an ...

Kinetics of enzymatic hydrolysis of methyl ricinoleate
Grasas y Aceites, 2015 Ricinoleic acid is an unsaturated hydroxy fatty acid that naturally occurs in castor oil in proportions of up to 85–90%. Ricinoleic acid is a potential raw material and finds several applications in coatings, lubricant formulations and pharmaceutical ...
