Regioselective analysis of triacylglycerols by lipase hydrolysis

Journal of the American Oil Chemists' Society, 1995
AbstractA modified procedure for the regiospecific analysis of triacylglycerols (TAG) with a 1,3‐specific lipase is described. After partial lipase hydrolysis of the triacylglycerol, the released free fatty acids (FFA) and 1,2(2,3)‐diacylglycerols (DAG) were isolated by thin‐layer chromatography (TLC) and converted to fatty acid methyl esters (FAME ...

Effect of cholera toxin on triacylglycerol lipase activity and triacylglycerol content of rat heart [PDF]

Canadian Journal of Physiology and Pharmacology, 1987
This study was performed to reexamine the effect of cholera toxin on total and intracellular alkaline lipoprotein lipase (LPL) activity in rat heart. In addition, the relationship between intracellular triacylglycerol (TG)lipase activity and TG content of cardiac tissue was determined in cholera toxin treated rats. One intravenous injection of cholera

Triacylglycerol lipase activity in the rabbit renal medulla

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1987
Although the renal medulla is rich in triacylglycerols, the lipolysis of these intracellular triacylglycerols by a renomedullary triacylglycerol lipase has not been directly demonstrated. The present study demonstrates triacylglycerol lipase activity localized in the particulate subcellular fractions of rabbit renal medullae.

Regulation and function of triacylglycerol lipases in cellular metabolism

Biochemical Journal, 2008
The ability to store energy in the form of energy-dense TAG (triacylglycerol) and to mobilize these stores rapidly during times of low carbohydrate availability (fasting or famine) or during heightened metabolic demand (exercise or cold-stress) is a highly conserved process essential for survival. Today, in the presence of nutrient excess and sedentary

Some properties of triacylglycerol lipase in chicken erythrocytes

International Journal of Biochemistry, 1986
Membrane-bound acid lipase was found in the chicken erythrocytes ghosts, having an optimum pH of 4.5. The membrane-bound lipase showed its maximum activity at 38 degrees C, and it was stable below 45 degrees C. The bound lipase was activated by octyl glucoside and 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS), but it was markedly ...

Identification of a triacylglycerol lipase in the diatom Phaeodactylum tricornutum

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2016
Diatoms accumulate triacylglycerols (TAGs) as storage lipids, but the knowledge about the molecular mechanisms of lipid metabolism is still sparse. Starting from a partial sequence for a putative TAG-lipase of the diatom Phaeodactylum tricornutum retrieved from the data bases, we have identified the full length coding sequence, tgl1.

Mechanistic model for the lipase-catalyzed alcoholysis of triacylglycerols [PDF]

Applied Catalysis A: General, 2006
Abstract The enzymatic alcoholysis of triolein and an oil highly rich in polyunsaturated fatty acid with ethanol to obtain 2-monoacylglycerols (2-MG) was studied. Two sn -1,3 specific lipases were used to catalyze this reaction: Lipozyme ® IM from Mucor miehei and lipase D from Rhizopus oryzae . The experimental results were acceptably fitted to

Phosphonate analogues of triacylglycerols are potent inhibitors of lipase

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1995
1,2-Dioctylcarbamoylglycero-3-O-p-nitrophenyl alkylphosphonates, with alkyl being methyl or octyl, were synthesised and tested as irreversible inhibitors of cutinase from Fusarium solani pisi and Staphylococcus hyicus lipase. Rapid inactivation of these enzymes occurred with a concomitant release of one mole of p-nitrophenol per mole of enzyme.

Hydrolysis of synthetic triacylglycerols by pancreatic and lipoprotein lipase

Lipids, 1974
AbstractThe stereochemical course of the hydrolysis of synthetic sn‐glycerol‐1‐palmitate‐2‐oleate‐3‐linoleate, sn‐glycerol‐1,2‐dipalmitate‐3‐oleate and their antipodes by pancreatic and milk lipoprotein lipase was investigated by thin layer and gas liquid chromatographies of the diacylglycerol intermediates.

Hydrolysis of emulsified mixtures of triacylglycerols by pancreatic lipase

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1999
Hydrolysis of the emulsified mixture of short-chain triacylglycerols by porcine pancreatic lipase in the presence of procolipase and micellar sodium taurodeoxycholate has been studied. Increase in the content of tributyrin and trioctanoin in the mixture with triacetin had highly cooperative effects on the formation of the interfacial lipase procolipase
