Product Overview :
Significance of Measurement: Hydroxyl radicals cause severe damage to proteins, nucleic acids, and lipids, leading to cellular dysfunction and metabolic disorders. Hydroxyl radical scavenging capacity is an important indicator of antioxidant activity in health products and pharmaceuticals.
Principle of Measurement: Hydroxyl radicals generated via the Fenton reaction oxidize Fe2+ to Fe3+, resulting in decreased absorbance at 536 nm. The degree of inhibition of absorbance decrease reflects the hydroxyl radical scavenging ability of the sample.
