Detailed Images
Guanine is an organic base that is widespread in the animal and the plant kingdom. The chemical name is 2-amino-6-oxo-purin. It is
colorless square crystals or crystalline powder. In the aqueous solution containing a large excess of ammonia, it will become
small diamond crystal after slowly evaporating the water. It has a melting point of 360 ℃ (partially decomposed and sublimated).
It can be dissolved in ammonia water, caustic soda and dilute mineral acid, slightly soluble in ethanol, ethyl ether, and
insoluble in water. It has a strong UV absorption. It is the major composition of guanosine and guanylate. Its hydrochloride
monohydrate is powdery crystals with water being loss at 100 ℃ and hydrogen chloride being loss at 200 ℃. It can be dissolved in
acidified water but is insoluble in water, alcohol, and ether. Guanine can be obtained through the hydrolysis of scale in
hydrochloric acid. It is an important base composition of nucleic acids, being one of the four major bases of DNA and RNA as well
as the compassion of various kinds of guanylate. Its N9 can be connected with the C1 of ribose or deoxyribose with β-glycosidic
bond to obtain guanosine or deoxy-guanosine.
