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

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

Zeta potential and dipole potential measures are direct operational methodologies to determine the adsorption, insertion and penetration of ions, amphipathic and neutral compounds into the membranes of cells and model systems. From these results, the

The lack of details in the hydration properties of lipid bilayers hinders the design of biomimetic systems that, as liposomes and vesicles, may be used for biotechnological and medical purposes. In this chapter, studies indicate water as a membrane d

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

It is known that phospholipase A2 (PLA2) hydrolyzes phosphatidylcholines (PC) producing lysophosphatidylcholine and fatty acids. The substrate of the enzymatic action is the sn2 acyl chain being Ca2+ ion an essential cofactor for the activation. Many

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

The influence of Phe on the surface pressure of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) monolayers at the air?water interface was studied at different initial surface pressures (26 and 40 mN/m) and two pHs (5.0 and 7.3) at constant tempera

Xanthone (Xa) and 1-OH Xanthone (1-OHXa) in 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) membranes increase the dipole potential. Results with 1,2-di-O-tetradecyl-sn-glycero-3-phosphocholine (Ether PC), lacking carbonyl groups, indicate that th
