A mesoscale model for quantitative phospholipid monolayer simulations at the air-water interface [PDF]
arXiv, 2021 A mesoscale model with molecular resolutions is presented for the dipalmitoyl-phosphatidylcholine (DPPC) and 1-palmitoyl-2-oleyl-sn-glycero-3-phosphocholine (POPC) monolayer simulations at the air-water interface using many-body dissipative particle dynamics (MDPD).

General model of phospholipid bilayers in fluid phase within the single chain mean field theory [PDF]
J. Chem. Phys. 140, 174903 (2014), 2014 Coarse-grained model for saturated (DCPC, DLPC, DMPC, DPPC, DSPC) and unsaturated (POPC, DOPC) phospholipids is introduced within the Single Chain Mean Field theory. A single set of parameters adjusted for DMPC bilayers gives an adequate description of equilibrium and mechanical properties of a range of saturated lipid molecules that differ only in ...

Transporting of a Cell-Sized Phospholipid Vesicle Across Water/Oil Interface [PDF]
, 2006 When a cell-sized water droplet, with a diameter of several tens of micro meter, is placed in oil containing phospholipids, a stable cell-sized vesicle is spontaneously formed as a water-in-oil phospholipid emulsion (W/O CE) with a phospholipid monolayer.

From supported membranes to tethered vesicles: lipid bilayers destabilisation at the main transition [PDF]
10.1209/epl/i2006-10145-2, 2006 We report results concerning the destabilisation of supported phospholipid bilayers in a well-defined geometry. When heating up supported phospholipid membranes deposited on highly hydrophilic glass slides from room temperature (i.e. with lipids in the gel phase), unbinding was observed around the main gel to fluid transition temperature of the lipids.

Discovery in space of ethanolamine, the simplest phospholipid head group [PDF]
, 2021 Cell membranes are a key element of life because they keep the genetic material and metabolic machinery together. All present cell membranes are made of phospholipids, yet the nature of the first membranes and the origin of phospholipids are still under debate.

Motional Coherence in Fluid Phospholipid Membranes [PDF]
Phys. Rev. Lett. 101, 248106 (2008) (4 pages), 2008 We report a high energy-resolution neutron backscattering study, combined with in-situ diffraction, to investigate slow molecular motions on nanosecond time scales in the fluid phase of phospholipid bilayers of 1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine (DMPC) and DMPC/40% cholesterol (wt/wt).

Journal of Lipid Research, 2022 Advanced liver diseases account for approximately 2 million deaths annually worldwide. Roughly, half of liver disease-associated deaths arise from complications of cirrhosis and the other half driven by viral hepatitis and hepatocellular carcinoma ...

FEBS Letters, 1988 Protein mediated phospholipid translocation through membranes has been observed in rat liver endoplasmic reticulum and in the plasma membrane of erythrocytes as well as in a few other cell membranes. Lipid translocation in plasma membranes is ATP dependent and selectively accumulates aminophospholipids on the inner monolayers.

Smooth/rough layering in liquid-crystalline/gel state of dry phospholipid film, in relation to its ability to generate giant vesicles [PDF]
, 2005 Morphological changes in a dry phospholipid film on a solid substrate were studied below and above the main transition temperature, between the gel and liquid-crystalline phases by phase-contrast microscopy and AFM. A Phospholipid film in the liquid-crystalline phase exhibits flat, smooth layering, whereas that in the gel phase shows rough, random ...

Multilayer of Phospholipid Membranes on a Hydrosol Substrate [PDF]
JETP Letters 92, 356 (2010), 2010 The molecular structure of a multilayer of 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC) adsorbed on the surface of the hydrosol of silica nanoparticles has been studied by the synchrotron radiation scattering method. According to the reflectometry data, the multilayer is formed by planar phospholipid bilayers with a thickness of 69 +/- 1 Angstrom ...
