Monoglycerides and Diglycerides Synthesis in a Solvent-Free System by Lipase-Catalyzed Glycerolysis

Applied Biochemistry and Biotechnology, 2008
Five lipases were screened (Thermomyces lanuginosus free and immobilized forms, Candida antarctica B, Candida rugosa, Aspergillus niger, and Rhizomucor miehei) to study their ability to produce monoglycerides (MG) and diglycerides (DG) through enzymatic ...

The polymorphism of diglycerides

Journal of the Science of Food and Agriculture, 1992
AbstractThe polymorphism of 1,3‐dipalmitin, 1,2‐dipalmitoyl‐sn‐glycerol, 1.2‐dipalmitoyl‐rac‐glycerol has been examined by X‐ray diffraction, IR spectroscopy and Raman spectroscopy and differential scanning calorimetry. The respective spectra and thermographs are presented for these polymorphs.

Determination of Ceramides and Diglycerides by the Diglyceride Kinase Assay

Analytical Biochemistry, 2001
This review will discuss the utilization of the diglyceride (DG) kinase assay as an analytical method that allows the simultaneous quantitation of DG and ceramide from cell and tissue samples. This enzymatic approach is sensitive, quantitative, and linear over a broad range (20 pmol to 20-25 nmol) for both classes of lipids.

Analysis of monoglycerides, diglycerides, sterols, and free fatty acids in coconut (Cocos nucifera L.) oil by 31P NMR spectroscopy.

Journal of Agricultural and Food Chemistry, 2008
Phosphorus-31 nuclear magnetic resonance spectroscopy (31P NMR) was used to differentiate virgin coconut oil (VCO) from refined, bleached, deodorized coconut oil (RCO). Monoglycerides (MGs), diglycerides (DGs), sterols, and free fatty acids (FFAs) in VCO

Quantitative analysis of sulfolipid (sulfoquinovosyl diglyceride) and galactolipids (monogalactosyl and digalactosyl diglycerides) in plant tissues

Analytical Biochemistry, 1968
Abstract A method has been developed for the quantitative and rapid estimation of sulfolipid and galactolipids in plant tissues. The procedure is based on the isolation of pure glycolipids by a combination of DEAE-cellulose column and thin-layer chromatography.

Acyl migration in diglycerides

Journal of the Chemical Society C: Organic, 1966
The equilibrium between 1,2-dipalmitin and 1,3-dipalmitin as a result of acyl migration has been studied using thin-layer chromatography and densitometry. When isomerisation is catalysed by potassium hydroxide, the composition of the equilibrium mixture varies with the temperature of the isomerisation.

The preparation of unsymmetrical diglycerides

Journal of the Chemical Society C: Organic, 1967
Racemic 1,2-di-O-acylglycerols containing stearic and palmitic acids were prepared from 1,2-di-O-acyl-3-O-2′-tetrahydropyranylglycerols by hydrolysis of the tetrahydropyranyl group with boric acid. The 1,2-di-O-acyl-3-O-2′-tetrahydropyranylglycerols were obtained by acylation of 3-O-2′-tetrahydropyranylglycerol which was prepared from glycerol 1,2 ...

Galactosyl-diglyceride from Actinomyces viscosus

Chemistry and Physics of Lipids, 1974
Abstract The glycolipids from Actionomyces viscosus were investigated. A 1-O-monogalactosyl-diglyceride was identified. Analysis of its fatty acids by mass spectrometry showed that they consisted largely of palmitic and stearic acids and their monounsaturated homologues.
