Applictions：
Enzyme Reactions
Detection and study of the active site of Cu,Zn-SOD
Many enzyme reactions involve one-electron oxidation steps with formation of paramagnetic transient state of the enzyme detectable by EPR.
Reaction Kinetics
Kinetics analysis of vitamin C antioxidant ability
Many chemical reactions involve the transfer of one electron. Each electron transfer results in an unpaired electron creating paramagnetic free radicals.
Photochemistry
Light degradation of hops in beer
The majority of photochemical reactions take place through free radical formation as intermediates. For example, hops used in the brewing process contain a mixture of active components that include humulones, cohumulones, adhumulones, beta acids and essential oils. Some forms of these components are photo-active.
