Abstract

Small-angle neutron scattering (SANS) measurements have been made to determine the structure of the small aggregates formed spontaneously by mixing 20 mM dipalmitoyl-PC (PC=phosphatidylcholine) with 5 mM diheptanoyl-PC in aqueous solutions at 30 °C. The Kratky-Porod plots shows that these small aggregates have disk-like structure with a bilayer thickness of about 46 Å. The most probable structure of these small aggregates is disk-like bilayer aggregates with a radius of 94.5 Å and a thickness of 44.3 Å, as determined by fitting the data with the disk model.
