Abstract Influence of pH on the extent of lipid peroxidation and the anti-oxidant potential of an organoselenium compound is explored. Acidosis increased the rate of lipid peroxidation both in the absence and presence of Fe (II) in rat's brain, kidney and liver homogenate and phospholipids extract from egg yolk. The organoselenium compound significantly protected lipids from peroxidation, both in the absence and presence of Fe (II). Changing the pH of the reaction medium did not alter the anti-oxidant activity of the tested compound. This study provides in vitro evidence for acidosis-induced oxidative stress in brain, kidney, liver homogenate and phospholipids extract and the anti-oxidant action of the tested organoselenium compound.
