  • Glycerol
  • For a bilayer of "high coverage" (80%), extensive exchange takes place between the CPNP components and the bilayer, and at steady state the surface layer comprises 72% glycerol monooleate and 8% DOPC, with no change in the solvent content. (nih.gov)
  • This effect was most pronounced for glycerol at sufficiently high concentrations, which displayed a comparatively enhanced capacity to induce cross-linking of lipid headgroups resulting in the formation of extensive hydrogen bonding bridges and the promotion of a dense cryosolvent layer across the phospholipid bilayer.

  • POPC
  • In particular, we study how the response differs, in relation to different chain unsaturation levels, by comparing mono-unsaturated 1-palmitoyl-2-oleoyl-phosphatidylcholine (POPC) and bi-unsaturated dioleoyl-phosphatidylcholine (DOPC) bilayers. (qmul.ac.uk)
  • Notably, for most properties, including bilayer area and thickness, lipid order parameters, lateral pressure profile, and curvature frustration energy, we observe significantly more pronounced effects for mono-unsaturated POPC than bi-unsaturated DOPC. (qmul.ac.uk)
  • concentration
  • For example, water passes through the bilayer by osmosis , following the concentration gradient , that is, moving from where there is lots of water, to where there is less. (everything2.com)
  • hydrogen
  • Closer examination exposed a number of effects on the lipid bilayer as a function of the molecular size and hydrogen bonding capacity of the cryosolvents. (edu.au)
  • Analyses of hydrogen bonds revealed that increased concentrations of the polyhydroxylated cryosolvents induced the formation of a cross-linked cryosolvent layer across the surface of the membrane bilayer. (edu.au)
  • interface
  • Thioester exchange was found to be a suitable reversible reaction to achieve rapid equilibration of dynamic combinatorial libraries at the egg phosphatidyl choline bilayer interface. (springeropen.com)
  • The methodology to perform dynamic combinatorial chemistry at the phospholipid bilayer interface has been developed. (springeropen.com)
  • Our results show that the kinetics of thioester exchange are comparable in bulk solution and at the bilayer interface, despite the different microenvironments of these two systems. (springeropen.com)
  • content
  • The phospholipid content of the gel phase was rich in dipalmitoylphosphatidylcholine or distearoylphosphatidylcholine, or was entirely Ca(dioleoylphosphatidylserine) 2 . (springer.com)
  • area
  • The large surface-area-to-volume ratio of chromatographic silica allows interrogation of a significant lipid bilayer area within a very small volume. (osti.gov)
  • mechanism
  • For bilayers of "low coverage" (55%), the exchange mechanism involves an initial adsorption of material from the CPNPs to fill in the bilayer defects. (nih.gov)
  • environment
  • However, the structure of phospholipids can be affected by the salinity and pH of the cell's surrounding environment. (bioexplorer.net)
  • In relation to its semipermeability, the phospholipid bilayer acting as a barrier between the interior and exterior cellular environment can in turn mediates the recognition process, communication, and signaling process among neighboring cells. (bioexplorer.net)
