The effect of interesterification on the bioavailability of fatty acids in structured lipids
(2013)
Fatty acid (FA) profile is a critical factor in the nutritional properties of fats, but, stereochemistry may also play a fundamental role in the rate and extent to which FAs are absorbed and become available. To better ...
How membrane lipids control the 3D structure and function of receptors
(AIMS Press, 2018)
Abstract: The cohabitation of lipids and proteins in the plasma membrane of mammalian cells is controlled by specific biochemical and biophysical rules. Lipids may be either constitutively tightly bound to cell-surface ...
Regulation of Bacillus subtilis DesK thermosensor by lipids
(Portland Press, 2013-01)
Temperature sensing is essential for the survival of living cells. The membrane-bound thermosensor DesK from Bacillus subtilis is a key representative of histidine kinases receptors able to remodel membrane lipid composition ...
Microemulsion extrusion technique: a new method to produce lipid nanoparticles
(SpringerDordrechtHolanda, 2013)
Lipid hydroperoxidation effect on the dynamical evolution of the conductance process in bilayer lipid membranes: A condition toward criticality
(American Chemical Society, 2020-08-04)
Cell membranes are one of the main targets of oxidative processes mediated by reactive oxygen species (ROS). These chemical species interact with unsaturated fatty acids of membrane lipids, triggering an autocatalytic chain ...
In vivo postprandial bioavailability of interesterified-lipids in sodium-caseinate or chitosan based O/W emulsions
(Elsevier, 2015)
Recent studies have shown that it should be possible to control lipid bioavailability through food
structural approaches. Nevertheless, the gastrointestinal-tract physiological conditions must also be considered.
To get ...
Polymorphism, crystallinity and hydrophilic-lipophilic balance of stearic acid and stearic acid-capric/caprylic triglyceride matrices for production of stable nanoparticles
(ELSEVIER SCIENCE BV, 2011)
There is an increasing interest in lipid nanoparticles because of their suitability for several administration routes. Thus, it becomes even more relevant the physicochemical characterization of lipid materials with respect ...
Structural characterization of phosphatidylglycerol model membranes containing the antibiotic target lipid II molecule: a Raman microspectroscopy study
(John Wiley & Sons Ltd, 2017-02)
Effects induced by the incorporation of lipid II (LII) molecule into phosphatidylglycerol (PG) membranes were studied by Raman microspectroscopy. Spectral behavior of multilayer vesicles in liquid crystalline and gel phases ...
Thermosensing via transmembrane protein-lipid interactions
(Elsevier Science, 2015-09)
Cell membranes are composed of a lipid bilayer containing proteins that cross and/or interact with lipids on either side of the two leaflets. The basic structure of cell membranes is this bilayer, composed of two opposing ...
