The interaction of four diacylglycerols (DAGs) with multilamellar phospholipid bilayers consisting either of dipalmitoylphosphatidylcholine (DPPC) or of a mixture of DPPC and bovine liver phosphatidylcholine (BL-PC) extracts was investigated by a combination of 31P and 2H NMR spectrometry. We found

Biochimica et biophysica acta, 1124(3), 273-278 (1992-03-25)
Production of [3H]1,2-dipalmitoylglycerol ([3H]DAG) from 1-palmitoyl-2-[9,10-3H]palmitoyl-sn-glycero-3-phosphocholine and [3H]phosphorylcholine from 1,2-dipalmitoyl-sn-glycero-3-[Me-3H]phosphocholine was studied using sonicated rat platelets. The formation of [3H]DAG and [3H]phosphorylcholine occurred at a comparable rate. [3H]Phosphorylcholine formation was dependent on the concentration of the substrate, platelet sonicates and

Chemistry and physics of lipids, 52(3-4), 163-170 (1990-02-01)
The acyl migration of 1,2-dipalmitoyl-sn-glycerol (1,2-DPG) to 1,3-dipalmitoylglycerol (1,3-DPG) in different states, neat, in the presence of egg yolk lecithin (sonicated and unsonicated) and on silica gel was studied. The isomerization was quantitated by scanning densitometry of charred TLC plates
F López-García et al.
Biophysical journal, 66(6), 1991-2004 (1994-06-01)
The phases and transition sequences for aqueous dispersions of mixtures of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1,2-dipalmitoyl-sn-glycerol (1,2-DPG) have been studied by differential scanning calorimetry, dynamic x-ray diffraction, freeze-fracture electron microscopy, 31P-nuclear magnetic resonance spectroscopy, and Fourier-transform infrared spectroscopy. The results have
S O Smith et al.
Biochemistry, 31(46), 11660-11664 (1992-11-24)
Diacylglycerols are minor constituents of membrane lipids, yet are essential in the activation and membrane association of protein kinase C. Solid-state 13C NMR experiments have been used to characterize the orientation of the glycerol backbone of dipalmitoylglycerol (DPG) and dipalmitoylphosphatidylcholine
