It is a polar molecule due to the presence of the carbonyl (C=O) and amino (NH₂) groups. The aromatic rings in guanine's structure make it a relatively stable molecule, but it can still undergo ...

8-Oxo-7,8-dihydroguanine (8-oxoG): An oxidized form of guanine that is a common marker of RNA oxidation and can lead to mutations and cellular dysfunction. RNA-binding Proteins: Proteins that bind ...

Recent studies have focused on the mechanisms by which radical cations, particularly those derived from guanine, react with singlet oxygen and other reactive species, leading to oxidative ...
