Abstract

This paper reported that a way of preparing superoxide dismutase (SOD) modified by lauric acid (LA-SOD) and study on stability of LA-SOD. The results showed that LA-SOD had high specific activity, high stability and high rate of recovery. The stability of LA-SOD in temperature, pH and human gastric juice was much higher than that of natural SOD. Because LA-SOD is kept for a long time at room temperature, it can widen the applied range of SOD and bring out considerable benificial results both in society and economy.
