1,25-Dihydroxyvitamin D Regulation of Triacylglycerol Accumulation in Differentiated Adipocytes
… the bioactive vitamin D metabolite, on triacylglycerol accumulation and lipid and glucose metabolism in differentiated adipocytes. To study this, 3T3-L1 adipocytes were differentiated for 9 days, followed by stimulation with 1,25(OH)2D (10 nM) or vehicle for 1-7 days. Results indicate …

Interplay of DGAT1, PDAT1 and DGAT2 Enzymes in Plant Triacylglycerol Assembly
… from acyl-CoA to diacylglycerol (DAG) forming triacylglycerol (TAG, a.k.a oils and fats). Most plants have at least two unrelated <em>DGAT</em> genes, <em>DGAT1</em> and <em>DGAT2.</em> Plants predominantly express only one during oil synthesis; the reason, however is not clear. A few studies …

Regulation of Diacylglycerol Acyltransferase-2 and Triacylglycerol Synthesis by Protein Ubiquitination
Triacylglycerol is the major source of stored 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 …

Effect of phytosterol enrichment on the crystallisation, physiochemical, and interfacial behaviour of bulk and emulsified milk fat triacylglycerol matrices
… the crystallisation process, emulsified milk fat triacylglycerols (TAG) packing expanded upon phytosterol enrichment, which was observed as an increase in the triple-chain length (3L). In bulk milk fat, both doublechain length (2L) and 3L TAG packing was seen during cooling; the 3L spacing also …

Investigating mechanisms of triacylglycerol synthesis induced by nitrogen depletion in the diatom Phaeodactylum tricornutum and characterising its diacylglycerol acyltransferases and phospholipid: diacylglycerol acyl transferase
… tricornutum (P. tricornutum) to accumulate triacylglycerol (TAG) and synthesise the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) has led to interest in their development for biofuels and human nutrition. Nitrogen depletion is a well-studied experimental system …

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 …

Biochemical changes associated with embryonic and larval development in the American lobster Homarus americanus Milne Edwards
… fatty acid composition. During embryogenesis, triacylglycerol supplied most of the energy and the fatty acid 20:5 was selectively utilized. Absence of prolonged cold incubation temperatures resulted in increased yolk reserves in newly hatched larvae. Weight, ash, protein, carbohydrate and lipid …

The influence of apolipoproteins on the interaction of hepatic lipase with high density lipoproteins / Neil J. Hime
… lipase mediated hydrolysis of phospholipids and triacylglycerol in spherical, apolipoprotein-specific reconstituted high density lipoproteins. The results show that apolipoproteins have a major impact on these processes.

Dietary long-chain polyunsaturated fatty acids affect plasma and tissue lipids in chickens
… + low density lipoprotein (VLDL + LDL) triacylglycerol concentrations which were lower than those for chickens fed CF. Tissue lipids from chickens fed LO contained more 20:5n3 compared with those fed SBO or CF. The amounts of 20:5n3 in tissues from chickens fed LO approached those found …

Value of Raisins for Reduction of Oxidative Stress, Endothelial Dysfunction, and Inflammation in Obesity
… and metabolic measures (free fatty acids (FFA), triacylglycerol (TAC), glucose, insulin). Urinary 8-isoPGF2α decreased 22% and ORAC increased 3% pre to post interventions combined. Postprandial metabolic responses differed by gender, males surpassed females for several measures: FFA, …

The Acute and Chronic Effects of Palmitic Acid-Rich Triacylglycerols on Cardiovascular Risk
… 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 changes in …

Characterization of metabolomic dynamics in synchronized Chlamydomonas reinhardtii cell cultures and the impact of TOR inhibition on cell cycle, proliferation and growth
… storage through an accumulation of starch, triacylglycerol and arginine. Interestingly, it seems that the conversion of carbon into triacylglycerol occurred faster than into starch after TOR inhibition, which may indicate a more dominant role of TOR in the regulation of TAG biosynthesis than …

This thesis elucidated the preparation and encapsulation of NA-enriched structured phospholipid (SPL), followed by the in vitro digestion and storage stability of encapsulated NA-enriched SPL. A preparation …

After a high monounsaturated fat diet, carriages of both PPARA Val162 and PPARG Ala12 alleles were associated with a greater reduction in plasma LDL-C and its proportion as small dense LDL, than after low fat diet. A …
