Degradation of Polysaccharide in Fenton Oxidative Cleavage Reaction and Their Antioxidant Activity

One of well known methods for degrading polysaccharide is to use the reactive oxygen species. The fenton reaction can produce aggressive OH-radical, which is one of potential species of ROS, from hydrogen peroxide in the presence of catalytic metal ions. Ascorbic acid acts as a potent antioxidant necessary to cope up these oxidative damages. We found that ascorbic acid also exhibits pro-oxidant characteristics in the presence of catalytic metal...
