Although these species are generated during normal cellular metabolism and participate in essential physiological processes like signal transduction and gene expression at low concentrations (Krishnamurthy et al., 2024), their excessive accumulation or insufficient scavenging leads to oxidative stress, causing damage to vital biomolecules and cellular structures
