This study shows that homocysteine inhibits the breakdown of hydrogen peroxide by catalase. Physiological concentrations of homocysteine inhibited catalase breakdown of hydrogen peroxide. The inhibition of catalase was by generation of the inactive catalase compound II and prevented by ethanol or NADPH but...
A cell organelle containing enzymes,such as catalase and oxidase,that catalyze the production and breakdown of hydrogen peroxide. 过氧物酶体一种包含酶的细胞器官,如催化剂和氧化剂,能够催化过氧化氢的生成和分解 In game birds, glucose 1-phosphate is formed by the breakdown of stored muscle glycogen, ...
which is caused by the over-production of reactive oxygen species (ROS), such as superoxide radical (•O2−), hydroxyl radical (•OH), and hydrogen peroxide (H2O2)11. However, endogenous antioxidant enzymes are insufficient to remove excessive ROS14,15, so introducing the exogenous ROS sca...
The mycelium can breakdown hydrogen peroxide present in its culture medium rapidly in a time-dependent manner. This breakdown depends on the composition of the culture medium, is not inhibited by inhibitors of catalase activity, but is considerably reduced by inhibitors of peroxidase, such as benz...

The bleaching reaction was not affected by hydrogen peroxide or hydrogen peroxide and 2,6-dichloroindophenol, but was slightly inhibited by linolenic acid. Catalase had no effect, but superoxide dismutase inhibited weakly. This bleaching was strongly inhibited by tiron and ascorbate. These results ...
