Implication

Narrative review outlines the formation, stability, and reaction pathways of reactive oxygen species in biological systems, highlighting their mechanistic involvement in chronic diseases.

Key Points

Review the generation pathways, chemical lifetimes, reactivities, and pathological roles of oxy-radicals and related reactive molecules in biological systems.
Synthesized biochemical and chemical literature regarding the properties of neutral radicals, radical ions, and non-radical reactive species.
Categorized reactive oxygen-containing molecules by oxidation states, half-lives, and capacity to initiate radical chain reactions.
Identified marked diversity in the stability of biological radicals, ranging from ultra-short-lived intermediates to stable species like nitrogen dioxide.
Showed that both radical and non-radical reactive oxygen products (such as singlet oxygen and ozone) drive pathological processes either through direct oxidation or by decomposing into secondary radical-generating hydroperoxides.
