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 ...
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 ...
Scientists have developed a probe for monitoring hydrogen peroxide levels in mice that enables them to track the progression of cancerous tumors or infectious diseases without harming the animals or ...
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) ...
The catalytic decomposition of hydrogen peroxide can be dangerous at high concentrations, but there is a safe version of Camille Schrier’s demonstration that is still fun. By Knvul Sheikh When she ...
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 ...
