Abstract

Superoxide dismutase (SOD) and catalase which are unique among enzymes can make the cellular detoxification of oxygen respiring organisims. Enzym SOD serve the purpose of muting the toxicity of molecular oxygen by catalytical scavenging the superoxide-free radical O2 with which some diseases can be caused. The maintenance of stable activity of intracellular Cu, Zn-SOD and Mn-SOD in human body has a relationship with the supplied bio-active minerals of Cu2+, Zn2+ and Mn2+ by the nutrition from natural food sources and food additives.
