Catalase enzymes play a pivotal role in cellular defence by decomposing hydrogen peroxide into water and oxygen, thereby mitigating oxidative stress. These oxidoreductases are ubiquitously found ...

Scientists report the safe synthesis of hydrogen peroxide (H2O2), an oxidizing agent used in multiple industries including semiconductors, using a new rhodium-based catalyst. The catalyst is based on ...

At high concentrations, reactive oxygen species - known as oxidants - are harmful to cells in all organisms and have been linked to aging. But a new study, has now shown that low levels of the oxidant ...

Peroxidases are enzymes that break down hydrogen peroxide in organisms. Since their discovery in 1998, the electron source of "peroxiredoxin 6-type" peroxidases for this reaction remained unclear. The ...

Bloodstains can be difficult to remove, especially when dried. Use cold water on a bloodstain as soon as possible, gently dabbing at the stain without rubbing. Hydrogen peroxide and oxygen or enzyme ...
