Guanine is a purine base that is found in the DNA and RNA of all living cells. It plays an important role as a component of the nucleic acid molecule, where it is paired with cytosine. Guanine is involved in many chemical reactions and biological processes, including protein synthesis and cell division. The lack of guanine can lead to deficiency symptoms such as hemolytic anemia or erythrocyte cytoplasmic inclusion bodies. Guanine has been shown to have chemiluminescent properties, which can be used to detect its presence in samples containing DNA or RNA. This reaction occurs when guanine reacts with hydrogen peroxide (H2O2) to form guanidine (HN=C(NH2)NH2). The reaction produces excited states that emit light at a wavelength of 395 nm when they return to their ground state.
