CAS 73-40-5

Guanine

Description:

Guanine is a purine nucleobase that plays a crucial role in the structure of nucleic acids, such as DNA and RNA. It is one of the four primary bases in DNA, pairing with cytosine through three hydrogen bonds, which contributes to the stability of the DNA double helix. Guanine is characterized by its molecular formula C5H5N5O, and it features a bicyclic structure composed of a fused imidazole and pyrimidine ring. This compound is typically found in the form of a white crystalline powder and is soluble in water. Guanine is essential for various biological processes, including protein synthesis and energy transfer, as it is a component of guanosine triphosphate (GTP), a key energy carrier in cells. Additionally, guanine can undergo various chemical modifications, influencing its role in cellular signaling and metabolism. Its CAS number, 73-40-5, uniquely identifies it in chemical databases, facilitating research and application in biochemistry and molecular biology.
