Chain arrangements in the gel state and the transition temperatures of phosphatidylcholines
Abstract:
Measures of chain length, inequivalence of chain length, and chain position have been incorporated into a parameter, D, which we call the "relative chain inequivalence." D has been calculated for a number of saturated phosphatidylcholines (PC) containing one type of chain (homoacid PC), saturated PC containing two different acyl chains (heteroacid PC), and heteroacid PC containing one saturated and one unsaturated chain. The gel to liquid-crystalline transition temperatures and D are related in a regular pattern, which suggests similarity of chain packing in the gel. This pattern may have useful predictive value.
