They are caused by the generation, oxidation or destruction of organic molecules during various processes in cells, tissues, and organs. <0x0A><0x0A>Detailed definition: Free radicals are highly reactive molecules with a high energy level, which can generate more energy than necessary. These molecules damage DNA, RNA, and proteins, leading to oxidative stress. They can cause inflammation, damage, and tissue destruction in the body. <0x0A><0x0A>Free radicals are part of the natural process of cellular repair and homeostasis, but excessive levels of free radicals can lead to chronic diseases like cancer, diabetes, and cardiovascular disease.
