When oxygen molecules split into single atoms that have unpaired electrons, they become unstable free radicals that seek other atoms or molecules to bond to. Free radicals are a natural byproduct ...

Free radicals play an important role in oxygen-dependent (aerobic) living systems. They are an important component in cell respiration and other vital cellular processes, but are also involved in ...

Medically reviewed by Marla Anderson, MD Free radicals are highly reactive and unstable molecules that are made by the body ...

Chronic exposure to hyperglycemia can lead to cellular dysfunction that may become irreversible over time, a process that is termed glucose toxicity ... Because reactive oxygen species are ...

By neutralizing free radicals and promoting antioxidant defenses ... Risks include barotrauma (pressure-related injuries), oxygen toxicity, and potential complications in individuals with certain ...

They also identified small molecules capable of breaking the chemical feedback loop that drives that toxicity. These compounds work by scavenging hydroxyl radicals—a type of reactive oxygen ...
