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.

CAS: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 purposesFormula:C5H5N5OPurity:Min. 97.5 Area-%Color and Shape:PowderMolecular weight:151.13 g/molGuanine extrapure, 99%
