Biobased surfactants

Jeremy Luterbacher, Songlan Sun, Stefania Bertella, Anastasiia Komarova

Compound of the general formula (Ia), (Ib) and (Ic) R50 and R60 are different form each other and are selected from the group consisting of -R70, -ZR70, -Z-OH, -Z-NH2, -Z-SH, -Z-OC(O)R70, -OC(O)R70, - COOH and its corresponding salts, -C(O)NH2, -C(O)NH-R70 ...

Amphiphilic nanoparticles generate curvature in lipid membranes and shape liposome-liposome interfaces

Francesco Stellacci, Francesca Olgiati

We show by molecular dynamics that amphiphilic Au nanoparticles (NP) with a diameter of 4 nm generate curvature in phosphatidylcholine lipid membranes. NPs generate negative curvature when they adsorb on the membrane surface but, as they get spontaneously ...

Inhibition of influenza virus activity by the bovine seminal plasma protein PDC-109

Christian Sieben

A number of viruses causing sexually transmissible diseases are transmitted via mammalian seminal plasma. Several components of seminal plasma have been shown to influence those viruses and their physiological impact. To unravel whether components of semin ...

Role and Function of Sphingomyelin Biosynthesis in the Development of Cancer

Giovanni D'Angelo

Sphingomyelin (SM) biosynthesis represents a complex, finely regulated process, mostly occurring in vertebrates. It is intimately linked to lipid transport and it is ultimately carried out by two enzymes, SM synthase 1 and 2, selectively localized in the G ...

Polycation Interactions with Zwitterionic Phospholipid Monolayers on Oil Nanodroplets Suspensions in Water (D2O) Probed by Sum Frequency Scattering

Sylvie Roke, Nikolay Smolentsev

By combining dynamic light scattering (DLS) measurements and infrared (IR) spectroscopy with the interface- and bond-specificity of vibrational sum frequency generation scattering (SFS) spectroscopy, we probe several structural aspects of how zwitterionic ...

Structure of outer membrane protein G in lipid bilayers

David Lyndon Emsley

beta-barrel proteins mediate nutrient uptake in bacteria and serve vital functions in cell signaling and adhesion. For the 14-strand outer membrane protein G of Escherichia coli, opening and closing is pH-dependent. Different roles of the extracellular loo ...

The lipidome associated with the gamma-secretase complex is required for its integrity and activity

Henning Paul-Julius Stahlberg, Patrick Fraering, Hermeto Gerber, Guillermo Miguel Garcia Osuna

gamma-Secretase is a multi-subunit membrane protease complex that catalyses the final intramembrane cleavage of the beta-amyloid precursor protein (APP) during the neuronal production of amyloid-beta peptides (A beta), which are implicated as the causative ...

Influence of the Adsorption of Phycocyanin on the Performance in DSS Cells: and Electrochemical and QCM Evaluation

Michael Graetzel, Jean-David Décoppet, Thomas Moehl

The influence of some coadsorbents and different pH values on the efficiency of DSS cells assembled with phycocyanin was evaluated using quartz crystal microbalance (QCM) and electrochemical techniques as impedance spectroscopy (EIS) and cyclic voltammetry ...

Lipid Builder: A Framework To Build Realistic Models for Biological Membranes

Matteo Dal Peraro, Thomas Lemmin, Giorgio Elikem Tamo, Christophe Bovigny, Nicolas Grégoire Maïno

The physical and chemical characterization of biological membranes is of fundamental importance for understanding the functional role of lipid bilayers in shaping cells and organelles, steering vesicle trafficking and promoting membrane-protein signaling. ...

Towards a kinetic model of the phospholipids biosynthesis of the yeast Saccharomyces cerevisiae

Vassily Hatzimanikatis, Meriç Ataman, Georgios Savoglidis, Iro Oikonomidi

Lipids, as vital eukaryotic cellular components, play a major role in cell, tissue and organ physiology. Alterations of lipid enzymes and metabolic pathways are related to many human diseases, such as cancer, diabetes and neurodegenerative diseases. In thi ...
