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.
