Guanina

Descrizione:

Guanina è una nucleobase purinica che gioca un ruolo cruciale nella struttura degli acidi nucleici, come il DNA e l'RNA. È una delle quattro basi primarie nel DNA, accoppiandosi con la citosina attraverso tre legami idrogeno, il che contribuisce alla stabilità della doppia elica del DNA. Guanina è caratterizzata dalla sua formula molecolare C5H5N5O e presenta una struttura biciclica composta da un anello di imidazolo e un anello di pirimidina fusi. Questo composto si trova tipicamente sotto forma di polvere cristallina bianca ed è solubile in acqua. Guanina è essenziale per vari processi biologici, inclusa la sintesi proteica e il trasferimento di energia, poiché è un componente del trifosfato di guanosina (GTP), un trasportatore di energia chiave nelle cellule. Inoltre, Guanina può subire varie modifiche chimiche, influenzando il suo ruolo nella segnalazione cellulare e nel metabolismo. Il suo numero CAS, 73-40-5, lo identifica in modo univoco nelle banche dati chimiche, facilitando la ricerca e l'applicazione in biochimica e biologia molecolare.

Guanine

CAS: 73-40-5

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. Guanidine also has electrochemical impedance spectroscopy properties, which can be used for analytical purposes
