โœฆ Synopsis

The sonicated dispersion of phospholipids in water is found to form a 1:1 molecular complex with iodine when the concentration of phospholipid is above the critical value (1.6ร— 10-5moldm-3). From thermodynamic as well as spectrophotometric studies, the electron donating property of several phospbolipids [phosphatidylethanolamine (PE), lyso PE (LPE), phosphatidylcholine (PC: earlier result), lyso PC (LPC) and sphingomyelin (SM)] have been compared. The kinetics of interaction in the case of Pc-iodine complex have also been studied. Results iadicate that the mode of lipid organization plays a significant role in the complex formation. The nature of this interaction as well as the site of interaction in phospholipids are identified.
