Chapter 3 Immiscible Langmuir monolayers: Interactions between the polar head groups of cholesterol and octylcyanobiphenyl
Mixed Langmuir monolayers are ideal systems to mimic biological membranes [1, 2]. Studies on mixed monolayers provide information about the interactions involved, miscibility and stability of the monolayer. It is known that cholesterol(Ch) is found in bilayer membranes and lipoproteins. Ch regulates the transport and barrier properties of the membranes [3]. Lung surfactant in the human body is ...
متن کاملInteraction between Cholesterol and Chitosan in Langmuir Monolayers
Chitosan incorporated in the aqueous subphase is found to affect the Langmuir monolayers of cholesterol, causing the surface pressure and the surface potential isotherms to become more expanded. The mean molecular area per cholesterol molecule in the condensed monolayer increases from 53 Å in the absence of chitosan to 61 Å for a concentration of 0.100 mg/mL of chitosan in the subphase. If addi...
متن کاملPolar head group interactions in mixed Langmuir monolayers.
We have investigated the miscibility in the mixed monolayers of cholesterol (Ch)-octyl cyano biphenyl (8CB) and cholesteryl acetate (ChA)-8CB using surface manometry and epifluorescence microscopic techniques. The main skeleton is the same both in Ch and ChA, whereas the polar head group is alcohol in Ch and ester in ChA. The 8CB molecule has a polar cyano as a terminal group and we probe its i...
متن کاملEffect of chiral interactions on the structure of Langmuir monolayers
Structural changes in monolayers of the enantiomer and the racemic mixture of 1-hexadecyl-glycerol with temperature and surface pressure variations are compared. On compression, both monolayers exhibit a variation of the tilt azimuth from the direction to the nearest neighbor to the next nearest neighbor. In the monolayer of the racemate, this variation occurs as a first order transition. In th...
متن کاملPhotosystem I in Langmuir-Blodgett and Langmuir-Schaefer monolayers.
Photosystem I (PSI) is a membrane protein complex that generates photoinduced electrons and transfers them across the thylakoid membrane during photosynthesis. The PSI complex, separated from spinach leaves, was spread onto the air-water interface as a monolayer and transferred onto a gold electrode surface that was precoated with a self-assembled monolayer (SAM). The electrochemical properties...
