Properties of unusual phospholipids, II: Synthesis, NMR studies and monolayer investigations of diacylglycerophosphocholines containing alpha-branched acyl chains.
Diacylglycerophosphocholines, containing various alpha-branched fatty acids, were synthesized and purified to homogeneity. The influence of the alpha-branched acyl chains on the monolayer packing properties of these phospholipids was studied by the Langmuir-Blodgett film balance technique. NMR investigations were used for conformational studies, including the determination of rotamer populations about the dihedral angles (theta 2, theta 4 and alpha 1) in the glycerol region of the diacylglycerophosphocholines.
