The triacylglycerol (TAG)-accumulating, hydrocarbon-degrading bacterium Rhodococcus opacus strain PD630 and chemically induced storage-deficient mutants derived from this strain were investigated for their capability to accumulate storage lipids in the cytoplasm during cultivation under nitrogen-limiting conditions. Acylglycerols were analysed by matrix-associated laser desorption ionization-ti...

The lipid composition of arterial walls changes during development, ageing and pathological processes. Preeclampsia is the most common pregnancy-associated pathological syndrome. It is accompanied by significant remodelling of extracellular matrix both in the umbilical cord vessels and in the surrounding Wharton’s jelly. The lipids of the umbilical cord were not studied till now, therefore it w...

The enzymatic reaction of soybean oil (SBO) triacylglycerides (TAGs) with ethyl ferulate (EF) produces the product feruloylated acylglycerols, alled SoyScreenTM as well as by-product fatty acid ethyl esters (FAEEs). Both the unreacted EF as well as the by-product FAEEs must be removed rom the mixture before the feruloylated acylglycerols can be used as natural sunscreens and/or antioxidants. Th...

Despite their important role in tissues, fluids and foods, the analysis of non-esterified fatty acids (NEFA) as methyl esters (NEFAME) is performed using expensive, cumbersome and time-consuming procedures that needs of isolation, fractionation and derivatization steps. However, Yi et al. [1] proposed a promising in situ, single-step procedure to analyze esterified fatty acids (EFA) and NEFA fr...

A quantitative model describing the kinetics of hydrolysis of rat chylomicron acylglycerols by bovine milk lipoprotein lipase has been developed using data from studies on rat lymph chylomicrons containing doubly labeled acylglycerols. The detailed analysis indicates that, in addition to hydrolysis from tri- to di-, di- to mono-, and monoacylglycerol to glycerol, and apparently direct hydrolysi...

The present investigation reports a study about the evolution, during ripening, of the fatty acid profile and the fatty acid composition in acylglycerols of three different fermented sausages industrially produced in the Calabria region (Southern Italy). Statistical analysis (ANOVA) was applied to the results obtained for the profiles to check all the differences between samples. The study comp...

Lipases are secreted into the culture medium by many bacteria and fungi. They catalyse not only the hydrolysis but also the synthesis of long-chain acylglycerols. Important uses in biotechnology include their addition to detergents, the manufacture of food ingredients, pitch control in the pulp and paper industry, and biocatalysis of stereoselective transformations. This makes them the most wid...

The floral oils of Diascia purpurea, Diascia vigilis, Diascia cordata, Diascia megathura, Diascia integerrima and Diascia barberae (Scrophulariaceae) were selectively collected from trichome elaiophores. The derivatized floral oils were analyzed by gas chromatography-mass spectrometry (GC-MS), whilst the underivatized samples were analysed by electrospray ionization mass spectrometry (ESI-MS) a...
