CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe have investigated the dimyristoylphosphatidylcholine system with a high concentration of butanol (two molecules per phospholipid) via X-ray diffraction, differential scanning calorimetry and density measurements. A lowering of the main transition temperature for the membrane/alcohol system has been observed. The phospholipid bilayer/alcohol system is characterised by a higher density value than the pure membrane, as determined by volumetric measurements. Analysis of diffraction patterns has shown the existence of a more packed structure due to the presence of alcohol. The area of polar head has also been estimated.
