摘要：
To improve its stability and lipophilicity, Cu,Zn-superoxide dismutase (SOD) was chemically modified with linoleic and alpha-linolenic acids using two different methods. Higher retained enzymatic activity has been observed compared with SOD modified by macromolecular substances. Enhanced heat stability, acid and alkali resistance, and anti-pepsin/trypsin ability of the modified SOD were observed compared with those of the natural enzyme, the apparent oil-water partition coefficient being especially increased. The results characterize SOD modified with polyunsaturated fatty acids as a promising pharmacological tool.
