The unique properties of vegetable oils from different plants utilized for food, industrial feedstocks, and fuel is dependent on the fatty acid (FA) composition of triacylglycerol (TAG). Plants can use two main pathways to produce diacylglycerol (DAG), the immediate precursor molecule to TAG synthesis: (1) De novo DAG synthesis, and (2) conversion of the membrane lipid phosphatidylcholine (PC) ...

Diacylglycerol (DAG) is an intermediate in metabolism of both triacylglycerols and membrane lipids. Probing the steady-state pools of DAG and understanding how they contribute to the synthesis of different lipids is important when designing plants with altered lipid metabolism. However, traditional methods of assaying DAG pools are difficult, because its abundance is low and because fractionati...

Acyl glucuronides are intrinsically reactive metabolites of carboxylate drugs, capable of undergoing hydrolysis, intramolecular rearrangement (isomerization via acyl migration), and intermolecular transacylation reactions. Transacylation with nucleophilic groups located on protein molecules leads to covalent drug-protein adducts. Protein adducts can also form from the rearrangement isomers via ...

SMS [SM (sphingomyelin) synthase] is a class of enzymes that produces SM by transferring a phosphocholine moiety on to ceramide. PC (phosphatidylcholine) is believed to be the phosphocholine donor of the reaction with consequent production of DAG (diacylglycerol), an important bioactive lipid. In the present study, by modulating SMS1 and SMS2 expression, the role of these enzymes on the elusive...

Diacylglycerol (DAG) has been reported to reduce the serum lipid and glucose levels more effectively compared with triacylglycerol (TAG). The present study examined the long-term effects of dietary DAG on rats with type 2 diabetic nephropathy (DN). The type 2 DN model was established by administering a high-fat and high-calorie diet along with an intraperitoneal injection of 35 mg/kg body weigh...

Dexamethasone/ascorbic acid/glycerolphosphate (DAG) and bone morphogenic protein (BMP)-2 are potent agents in cell proliferation and differentiation pathways. This study investigates the in vitro interactions between dexamethasone and BMP-2 for an osteoblastic differentiation of mesenchymal stem cells (MSCs). Bone marrow-derived human MSCs were cultured with DAG (group A), BMP-2 + DAG (group B)...

The 1,2-diacylglycerol (DAG) mass content was measured in thrombin-stimulated human platelets. Thrombin stimulates a biphasic accumulation of DAG, with an early phase reaching a peak at 10 s and a later phase reaching a peak at 2-3 min. The time course of first-phase DAG production corresponded well to that of Ins(1,4,5)P3 formation, which was rapid and transient. The second phase of DAG accumu...

Constructing Directed Acyclic Graph (DAG) on a graph is one of the fundamental problems of graph theory. We propose a self-stabilizing protocol for DAG construction on mobile ad-hoc network (MANET) and show that it can construct a DAG which has better property than known one. Furthermore, we evaluate our protocol by applying it to geocast protocol on MANET. Our computer simulation results show ...

Mono-, diand triacylglycerol (MAG, DAG, TAG), sterol ester (SE), free sterol (S) and free fatty acid (FFA) standards were analyzed in the presence of ammonium ions and ammonia by flow injection MS2 and MS3, and by normal phase-liquid chromatography (NP-LC) MS2 positive electrospray ionization (ESI) mass spectrometry (MS). The MS data recorded for ammonium adducts ([M+ NH4]) of TAGs, DAGs, and M...

Small molecule regulation of cell function is an understudied area of trypanosomatid biology. In Trypanosoma brucei diacylglycerol (DAG) stimulates endocytosis of transferrin (Tf). However, it is not known whether other trypanosomatidae respond similarly to the lipid. Further, the biochemical pathways involved in DAG signaling to the endocytic system in T. brucei are unknown, as the parasite ge...
