Conversion of triacylglycerols into monoacylglycerols by penicillium roquefortii
… specificity to the sn-2 position in the original triacylglycerols (TAGs) and one L3-specific during growth of the fungal mycelium. In addition, flavour compounds, methyl ketones and y-lactones, were found in solid-state culture. The composition of the MAGs formed by lipolysis using a commercial …

The Acute and Chronic Effects of Palmitic Acid-Rich Triacylglycerols on Cardiovascular Risk
The thesis investigated the hypothesis that differences in the triacylglycerol structure of palmitic acid-rich fats influence lipid metabolism and glucose/insulin homeostasis. A review of the literature and acute test meal and chronic feeding studies were conducted in human subjects. Postprandial …

Process design and modeling for the production of triacylglycerols (TAGs) in Rhodococcus opacus PD630
… and kinetics of the accumulation of triacylglycerols (TAGs) in cells. In this process, accumulation of TAG is stimulated when a carbon source is present in the medium in excess and the nitrogen source is limiting growth. Under controlled fermentation conditions the organism …

Development of an LC-MS/MS method for the analysis of triacylglycerols from meat and application in the discrimination of cooked meat products
… (RP HPLC) separation of animal fat triacylglycerols (TAGs) has been developed for coupling with atmospheric pressure chemical ionization tandem mass spectrometry using an ion trap mass spectrometer. The method developed offers significant improvements on existing methods for TAG …

Dietary long-chain polyunsaturated fatty acids affect plasma and tissue lipids in chickens
… of varying combinations of CF and MO on plasma triacylglycerols in broiler chickens. As the amount of dietary n-3 fatty acids and the polyunsaturate:saturate ratio increased, the concentration of triacylglycerols in plasma and the plasma VLDL + LDL fraction decreased. On the other hand, plasma …

Studies on soil and microbial lipases
… capacity, or organic matter. The addition of triacylglycerols to soil samples induced microbial production of lipase resulting in triacylglycerol degradation and associated oxygen consumption. With tallow applied to a Hamilton clay loam topsoil sample at the rate of 2.5 mg g⁻¹ and incubated at …

Synthetic and analytical investigations related to vegetable oils and fats.
… along two lines: analysis and synthesis of triacylglycerols. A new application is reported in the use of the infrared detector in HPLC for the detection and preparative and quantitative separation of triacylglycerols of seed fats and oils, acylglycerols from lipolysis mixtures and synthetic …

Evaluation of the effect of growth conditions on lipid production by Papiliotrema laurentii UFV-1 in culture media containing xylose
… vegetable oils are currently used as a source of triacylglycerols in the biodiesel production. Nevertheless, its production from these oils competes with food production for both arable lands and water. In addition, the vegetable oil features are affected by climatic conditions. These drawbacks …

Micro lipid droplet precursors of milk lipid globules
… suggested a possible translocation pathway of triacylglycerols from the rough endoplasmic reticulum to cytoplasmic lipid droplets. The micro lipid droplets seem to provide triacylglycerols to support growth of cytoplasmic lipid droplets. In addition, morphological evidence suggested that these …

The circadian role of Pex5 in glial cells and implications of Pex5 in sleep behavior and brain lipidome
… knockdown, with glia impacting sphingolipids and triacylglycerols, and neurons impacting phospholipids. The cell-type specificity of these Pex5 phenotypes highlights unique roles for peroxisomal import in both sleep and lipid metabolism in the brain.

Microstructural properties of isothermal palm oil crystallization
… that is influenced by the chemical composition (triacylglycerols and minor components) of the crystallizing fat as well as the processing conditions (time, temperature, shear). Palm oil, one of the largest vegetable oils worldwide, was selected as a substrate for this study. A first part of the …

dLipin-A Link between Lipid Metabolism, Glucose Homeostasis and Growth in Drosophila melanogaster
… enzymes (PAP) in the synthesis of neutral fats (triacylglycerols, TAG) and as transcriptional co-regulators that affect the expression of genes involved in lipid and fatty acid metabolism. Thus, they play central roles in metabolic control. Disruption of Lipin function has been implicated in …

PNPLA3 P.I148M VARIANT INCREASES LIPID DROPLETS NUMBER AND SIZE IN PATIENT-DERIVED LIVER ORGANOIDS
… which are essential for LDL loading and triacylglycerols export from the liver and whose levels drop during MASLD development; highlighting an unbalance towards lipid species that are proinflammatory and pro-apoptotic in Hep-HLO homozygous for PNPLA3 rs738409. Overall, these data …

Defining the metabolic effect of peroxisome proliferator-activated receptor δ activation
… characterised by the mobilisation and release of triacylglycerols (TAGs) into circulation as an energy source for peripheral tissues whereas PPAR gamma activation was defined by a reduction and sequestration of circulating TAGs. This thesis has better characterised the role of the PPARs as master …

Development of Mass Spectrometric Methods for the Analysis of Components and Complex Interactions in Biological Systems
… and diacylglycerols, with a smaller extent of triacylglycerols. The major polar phosphorylated lipids were identified in the tear extract revealing that sphingomyelin based species were being expressed in the dry eye condition. The major proteins were determined to be the lower molecular weight …

Regulation of Diacylglycerol Acyltransferase-2 and Triacylglycerol Synthesis by Protein Ubiquitination
… energy in humans, yet, excessive accumulation of triacylglycerols in tissues leads to obesity, diabetes and heart disease. Triacylglycerol synthesis is catalyzed by diacylglycerol acyltransferase (DGAT) enzymes, DGAT1 and DGAT2. Although recent studies have shed light on the metabolic functions of …

The Impact of a Controlled 10-Week Pistachio Feeding Crossover Trial on Blood Lipids and Measures of Adiposity
… were found between diet treatments for triacylglycerols (TAG) (p=0.6), TC (p=0.5), low-density lipoprotein cholesterol (LDL-C) (p=0.4), high-density lipoprotein cholesterol (HDL-C) (p=0.9), TC/HDL-C (p=0.7), body weight (p=0.8), BMI (p=0.9), waist circumference (WC) (p=0.4), or total …

Eragrostis nindensis: unravelling senescence in an African desiccation tolerant grass
… non-senescent tissue, particularly unsaturated triacylglycerols. It was proposed that lipid droplets that accumulated during drying were stabilised through, in part, the protein expression of oleosin. These lipid droplets appeared to provide a mechanical stabilisation and energy-providing role …
