Guanine is an organic base, widely found in animals and plants. The chemical name is aminooxypurine, colorless square crystal or crystalline powder, in In an aqueous solution containing a large excess of ammonia, slowly evaporate the water to obtain small rhombus crystals with a melting point of ℃ (decomposition and partial sublimation). Soluble in ammonia, caustic alkali and dilute mineral acid, slightly soluble in ethanol and ether, insoluble in water , has strong absorption of ultraviolet rays, and is a component of guanosine and guanylic acid. Its hydrochloride is a monohydrated powdery crystal, which loses water at ℃ and hydrogen chloride at ℃. It is soluble in acidified water and insoluble in Water, ethanol, ether. Guanine can be obtained from fish scales through hydrochloric acid hydrolysis. It is an important base that makes up nucleic acids. It is one of the main bases in and among species, and is also a component of various guanosine acids. It is closely related to ribose or deoxyribose It is connected with glycosidic bonds to form guanosine or deoxyguanosine.
The chemical composition is aminoketopurine. Together with adenine, it constitutes the two main purine bases in nucleic acids. It is combined with ribose or deoxyribose through glycosidic bonds and guanosine. Glycoside or deoxyguanosine, its triphosphate compound is guanosine triphosphate or deoxyguanosine triphosphate respectively, which are the precursors of guanine in the biosynthesis of ribonucleic acid and deoxyribonucleic acid.
Chemical Properties Five-color needle-shaped Crystalline or amorphous powder. ℃ (decomposition). Easily soluble in acid and alkali, slightly soluble in ethanol, ether, insoluble in water.
Uses Biochemical research and acyclovir intermediates and thioguanine, ring-opening Inspection items and indicators in the quality inspection sheet of guanine
