AC CONDUCTION STUDIES IN DIASTASE

Electrical properties of enzymes are of paramount importance for their biological activity. As an attempt to understand the charge transport phenomena in enzyme diastase ac conduction has been studied at five d ifferent temperatures, at room temperature 26 degrees C and 40 degrees C to 70 degrees C in step of 10 degrees C, in the frequency range 562 Hz-1.78 MHz, using a Hewlett-Packard impedance analyser. From results on frequency dependence of ac conduction it may be concluded that the mechanism responsible for the conduction process could be electronic h opping. The temperature dependence of ac conduction indicates the role of bound water molecules for the hopping conduction mechanism in dias tase.
