Description
Summary:Statistical analysis of quantitative structure—property relationships (QSPR) for the phase transition gel—liquid crystal (main phase transition) temperatures ( T m ) in hydrated vesicle bilayers of diacyl phosphatidylcholines (PC) and diacyl phosphatidylethanolamines (PE) with saturated acyl chains was carried out. Multiple regression equations relating the T m values to the volumes of the hydrocarbon fragments of the sn -1 and sn -2 acyl chains show that the acyl groups influence the transiton temperatures T m in different manner, the effect of the sn -2 group being predominant. The transition temperatures T m of saturated phosphatidylethanolamines and diacyl phosphatidylglycerols can be predicted using the T m values calculated for the corresponding diacyl phosphatidylcholines.
