Quinone

Quinones are a type of organic compounds characterized by a ring structure containing oxygen atoms, often derived from aromatic compounds like benzene. They play important roles in biological systems, especially in electron transport chains that generate energy in cells. Quinones act as electron carriers, helping transfer electrons during metabolic processes. They are also found in some natural pigments and can serve as antioxidants, protecting cells from damage. Their chemical structure and ability to accept and donate electrons make quinones vital in various physiological functions and industrial applications such as dyes and pharmaceuticals.
