The kinetic parameters for the dissociation of the amylose-1-􀀁-lysophosphatidilcholine complex were studied by differential scanning calorimetry, using the Borchardt?Daniels and dynamic methods. The reaction order was found to be close to 1 with an activation energy of 419 kJ/mol and the results were verified by an isothermal method; it was found that the activation energy increases for increasing water content. Two endotherms were obtained in the isothermal experi-ments, suggesting the presence of two forms of the complex, one more kinetically stable than the other.
