Water Behavior at the Phase Transition of Phospholipid Matrixes Assessed by FTIR Spectroscopy

Autor: Antonio Sebastian Rosa, María de los Ángeles Frías, Edgardo Anibal Disalvo

Publikováno v: The Journal of Physical Chemistry B. 124:6236-6244

Lipid membranes are one of the most important biological matrixes in which biochemical processes take place. This particular lipid arrangement is driven by different water disposition interacting with it, which is related to different water states wi

Updates of the mosaic fluid membrane model implicitly sustain the paradigms that bilayers are closed systems conserving a state of fluidity and behaving as a dielectric slab. All of them are a consequence of disregarding water as part of the membrane

Interaction of chlorogenic acid with model lipid membranes and its influence on antiradical activity

Autor: Jimena del Pilar Cejas, Maria de Los Angeles Frias, Mónica A. Nazareno, Antonio Sebastián Rosa, Edgardo Anibal Disalvo

Publikováno v: Biochimica et biophysica acta. Biomembranes. 1863(1)

Chlorogenic acid (CGA) is a strong phenolic antioxidant with antibacterial properties composed by a caffeoyl ester of quinic acid. Although a number of benefits has been reported and related to interactions with the red blood cell membranes, details

Fluorescence spectroscopy and Molecular Dynamics results show that cholesterol reduces water along the chains in ether lipids by changing the water distribution pattern between tightly and loosely bound water molecules. Water distribution was followe

Publikováno v: Journal of materials chemistry. B. 5(40)

In this study, a NE-U22 vibrating mesh Omron nebulizer was used to deliver the Lissamine™ rhodamine B 1,2-dihexadecanoyl-sn-glycero-3-phosphoethanolamine triethylammonium salt (Rh-PE) and 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS)

Publikováno v: The Review of scientific instruments. 90(12)

Water plays a key role in the functioning of natural and synthetic molecular systems. Despite several hydration studies, different techniques are employed individually for monitoring different physical features such as kinetics, dynamics, and absorpt

Correlation between the hydration of acyl chains and phosphate groups in lipid bilayers: Effect of phase state, head group, chain length, double bonds and carbonyl groups

This paper demonstrates by means of FTIR/ATR analysis that water molecules intercalate at different extents in the acyl chain region of lipid membranes in correlation with the hydration of the phosphate groups. This correlation is sensible to the cha

Publikováno v: Colloids and Surfaces B: Biointerfaces. 142:199-206

Temperature dependence of the zeta potential (ZP) is proposed as a tool to analyze the thermotropic behavior of unilamellar liposomes prepared from binary mixtures of phosphatidylcholines in the absence or presence of ions in aqueous suspensions. Sin

Publikováno v: Colloids and surfaces. B, Biointerfaces. 174

Saccharomyces cerevisiae is a type of yeast, widely used in diverse biotechnological food-beverage processes. Although the performance of an industrial fermentation process depends largely on the number of cells, it is necessary to consider the physi

Interaction of Phenylalanine with DPPC Model Membranes: More Than a Hydrophobic Interaction

Autor: Antonio Sebastián Rosa, María de los Ángeles Frías, Edgardo Anibal Disalvo, Andrea Carmen Cutró

Publikováno v: The Journal of Physical Chemistry B. 119:15844-15847

The negative free energy previously reported is explained by the stabilization of a PC-Phe (phosphocholine-phenylalanine) complex in the presence of water shown by the decrease in the symmetric stretching frequency of the phosphate group of the lipid
