Videofree radical

A free radical is a highly reactive atom or group of atoms characterized by having at least one unpaired electron. This instability causes them to steal electrons from nearby molecules, a process that can lead to significant cellular damage in the human body. This lesson explores the chemical nature of these particles and their biological impact, including how antioxidants work to neutralize them. Learn about the relationship between pollution, oxidative stress, and the behavior of these high-energy particles. Watch the lesson to master the terminology and science behind free radicals.
