Introduction:
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, , 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
Function:
Guanine is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA). In DNA, guanine is paired with cytosine. With the formula C5H5N5O, guanine is a derivative of purine, consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds. Being unsaturated, the bicyclic molecule is planar. The guanine nucleoside is called guanosine.
Used as a pharmaceutical intermediates.
It can be used for biochemical studies.
It can be used as the intermediates of the antiviral drugs acyclovir.
It can be used as the intermediate of thioguanine and open-ringed guanine.
Application:
Guanine has multiple uses. Crystalline guanine is extracted from the scales of some fishes. It is found to have many uses in the cosmetics industry. Crystalline guanine is added in various products like shampoos, where it provides a pearly shimmering effect. It is also used in nail polish and eye shadow to bring shimmering lustre. Facial treatments use the droppings, or guano, from Japanese nightingales. This is currently the flavor in New York, because the guanine in the droppings gives a clear and "bright" skin tone. Crystalline guanine is also used in metallic paints, simulated pearls and plastics.
