Most college biology labs focus on microscopes and Petri dishes, but this semester, students at Texas Wesleyan University are ...

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 ...

Hydrogen peroxide is known as a corrosive chemical and is sometimes used as a disinfectant. But scientists have now found that an enzyme in the lining of the gut can generate the production of ...

These form the body’s endogenous defence mechanisms to help protect against free radical-induced cell damage. The antioxidant enzymes – glutathioneperoxidase, catalase, and superoxide dismutase (SOD) ...

What you’re seeing, when hydrogen peroxide fizzes up on contact with blood, is a desperate stuggle for life. An enzyme in your blood, and most other living things, rips hydrogen peroxide apart – but ...

AN endo-enzyme system in tea leaf which could oxidize tea tannins directly was recently reported by Sreorangachar 1. The enzyme remained bound to the tissue after exhaustive washing with water or ...
