Abstract
A strong decrease of the bilayer bending elastic modulus, k(c), has be en experimentally established for dimyristoyl and dipalmitoyl phosphat idylcholine, when the liquid-crystal-gel phase transition temperature is approached from above. This phenomenon may be due to local-curvatur e-induced changes in the transition temperature. In the liquid-crystal phase, the bending modulus, k(c), significantly increases as a functi on of the lipid chain length for dilauryl, dimyristoyl and dipalmitoyl phosphatidylcholine.
