WebNov 7, 2024 · Hydroxyl radical (OH •) is one of the most important free radicals as it is extremely reactive with almost all type of biomolecules including amino acids, sugars, lipids and nucleotides. Most ROS are usually converted to hydroxyl radical. Thus, it is usually the final mediator of most free radical induced tissue damage [ 17 ].
