Aqueous solution of OPPC multilayers was studied by Raman scattering i
n a wide range of temperatures. A polymorphism similar to that of olei
c acid was encountered. In particular: the L-c(II) and L-c(I) forms we
re identified. This polymorphism is largely due to the double bond of
the oleyl chain in the sn-1 position. It was shown that the L-c(II) fo
rm of OPPC has a greater packing that the rippled phase of saturared l
ipid DPPC. (C) 1998 Published by Elsevier Science Ireland Ltd. All rig
