“…Electron microscopy, light scattering, fluorescence, radioisotopic techniques and 1H NMR experiments performed using bipolar lipids of Sulfolobus solfataricus have shown that for closed structures to be formed it was necessary in some cases to mix bipolar lipids with monopolar lipids (2)(3)(4). Table 1 In order to predict the organization of these lipids in the membrane we extended the Israelachvili theory to bipolar-monopolar lipid mixtures (5).…”

“…The film thickness was determined by AFM to 3.2nm ± 0.8nm. From the molecular structure of the TL [8,9], it can be concluded that the lipid is organised mainly in an uprightstanding conformation. The covalent coupling process could be confirmed by FTIR spectroscopy, where new peaks at 1509 cm -1 and 1541 cm -1 , which corresponds to the C=N valence oscillations of cyanuric chloride, became visible.…”

We report the surface modification of a cellulose dialysis membrane by tetraether lipids and silver colloids to improve the antiadhesive and antibacterial properties of the biopolymer. The lipid was covalently attached to the membrane via the bivalent linker cyanuric chloride. The biologically evaluation show that the adhesion of serum components as well as bacteria, was decreased by this novel coating.

'H NMR, DSC and UV studies of DMPC (1,2-dimyristoyl-sn-glycero-3-phosphocholine) vesicles have demonstrated the favourable physicochemical properties of the transmembrane phospholipid probes 1 a and 1 b for membrane topographical studies. In particular, in the presence of a physiological amount of cholesterol, only one transmembrane conformation is observed. The use of 1 a and cholesterol together for photolabelling experiments in DMPC vesicles led to a re-the myristoyl chains functionalized at markable improvement in the regioselec-C 11, C 12 and C 13 made up 95 % of the tivity of cross-linking between 1 a and total photolabelled myristates, and DMPC, and between 1 a and cholesterol : cholesterol was principally functionalized at the C 25 position on the side-chain. This indicates the formation of a highly ordered bilayer structure and proves directly the orientation of cholesterol perpendicular to the membrane plane with its chain terminal buried in the middle of the bilayer.
