Application

Spin trap reagent used to measure ethanol oxidation to 1-hydroxyethyl radical (HER) which can bind to protein. Has also been used in studies of DNA methylation, iron-mediated polyunsaturated fatty acid peroxidation, and free-radical formation by Alzheimer β-amyloid peptide. The formation of hydroxyl radical in chondrocytes and cartilage has been detected using POBN.

Lipid peroxidation is a well-known process that has been implicated in many diseases. Recent evidence has shown that mitochondrial cholesterol levels are increased under specific conditions, making it an important target for peroxidation inside the mitochondria. Cholesterol peroxidation generates, as
