Electrostatic interaction between proteins and polysaccharides: Physicochemical aspects and applications in emulsion stabilization
(2019-01-02)
Colloidal particle systems based on natural biopolymers are widely used in food industries and their production can involve an emulsification step during processing, which is induced by interaction of a primary emulsion, ...
Electrostatic potentials and polarization effects in proton-molecule interactions by means of multipoles from the quantum theory of atoms in molecules
(WILEY-BLACKWELLHOBOKEN, 2013-08-02)
Some atomic multipoles (charges, dipoles and quadrupoles) from the Quantum Theory of Atoms in Molecules (QTAIM) and CHELPG charges are used to investigate interactions between a proton and a molecule (F2, Cl2, BF, AlF, ...
Electrostatic Interactions Are Not Sufficient to Account for Chitosan Bioactivity
(AMER CHEMICAL SOC, 2010)
Recent studies involving chitosan interacting with phospholipid monolayers that mimic cell membranes have brought molecular-level evidence for some of the physiological actions of chitosan, as in removing a protein from ...
Electrostatic interactions at the microscale modulate dynamics and distribution of lipids in bilayers
(Royal Society of Chemistry, 2017-02)
For decades, it has been assumed that electrostatic long-range (micron distances) repulsions in lipid bilayers are negligible due to screening from the aqueous milieu. This concept, mostly derived from theoretical calculations, ...
An improved proximity force approximation for electrostatics
(Academic Press Inc Elsevier Science, 2012-08)
A quite straightforward approximation for the electrostatic interaction between two perfectly conducting surfaces suggests itself when the distance between them is much smaller than the characteristic lengths associated ...
Similar structures but different mechanisms: Prediction of FABPs-membrane interaction by electrostatic calculation
(Elsevier Science, 2012-07)
The role of fatty acid binding proteins as intracellular fatty acid transporters may require their direct interaction with membranes. In this way different mechanisms have been previously characterized through experimental ...
Overcoming electrostatic repulsions during amyloid assembly: Effect of pH and interaction with divalent metals using model peptides
(Academic Press Inc., 2017)
© 2017 Elsevier Inc. Amyloids are polypeptide aggregates involved in many pathologies including Alzheimer's disease. Amyloid assembly is a complex process affected by different interactions including hydrogen bonding, van ...
Understanding the role of electrostatic interactions on the association of 5-fluorouracil to chitosan-TPP nanoparticles
(2022-05-05)
Judicious design strategies should be considered powerful tools to better control the properties of chitosan (CS) and tripolyphosphate (TPP) particles. This study focused on understanding the role of the charge properties ...
Studies on electrostatic interactions within model nano-confined aqueous environments of different chemical nature
(Springer, 2017-09)
We study the potential of mean force for pairs of parallel flat surfaces with attractive electrostatic interactions by employing model systems functionalized with different charged, hydrophobic and hydrophilic groups.We ...
