Hydrogen peroxide (H2O2) is a well-documented component of living cells. It plays
important roles in host defense and oxidative biosynthetic reactions. In addition there is …

minimized by the action of antioxidant defence enzymes. In fact, H2O2 is poorly reactive in …

Abstract Hydrogen peroxide (H 2 O 2) can diffuse far from the site of production to
intracellular locations where biological effects may be greater. The diffusion range is …

Intracellular levels of H2O2 in BHK-21 cells are not static but decline progressively with cell
growth. Exposure of cells to inhibitors of catalase, or glutathione peroxidase, not only …

The concentration of hydrogen peroxide (H 2 O 2) in blood and plasma is a measurement
that has often been made, but the absolute values remain unsettled due the great variability …

The formation of hydroxyl radical (OH·) from the oxidation of glutathione, ascorbic acid,
NADPH, hydroquinone, catechol, and riboflavin by hydrogen peroxide was studied using a …

Instability of hydrogen peroxide solutions was noted during the experimental exposure of
human cells in culture to hydrogen peroxide in experiments designed to study the …

Cells have a wide range of capacities to remove extracellular hydrogen peroxide. At higher
concentrations of extracellular H 2 O 2 (micromolar) the rate of removal can be …

To investigate the mechanisms of H2O2adaptation in mammalian cells, we exposed human
U937 leukemia cells to 0.05 mM H2O2. This treatment significantly suppressed cell death …
