CAS 73-40-5

Guanina

Descrição:

Guanina é uma nucleobase purina que desempenha um papel crucial na estrutura dos ácidos nucleicos, como o DNA e o RNA. É uma das quatro bases primárias no DNA, emparelhando-se com a citosina através de três ligações de hidrogênio, o que contribui para a estabilidade da dupla hélice do DNA. Guanina é caracterizada pela sua fórmula molecular C5H5N5O, e apresenta uma estrutura bicíclica composta por um anel de imidazol e um anel de pirimidina fundidos. Este composto é tipicamente encontrado na forma de um pó cristalino branco e é solúvel em água. Guanina é essencial para vários processos biológicos, incluindo a síntese de proteínas e a transferência de energia, pois é um componente do trifosfato de guanosina (GTP), um transportador de energia chave nas células. Além disso, Guanina pode passar por várias modificações químicas, influenciando seu papel na sinalização celular e no metabolismo. Seu número CAS, 73-40-5, o identifica de forma única em bancos de dados químicos, facilitando a pesquisa e aplicação em bioquímica e biologia molecular.

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
