The controlled synthesis of microplatelets or nanoplatelets of the thermodynamically metastable β form of anhydrous guanine (β-AG) exposing the (100) plane in the presence of additives, twinned crystals, and the occlusion of hypoxanthine in β-AG were investigated to mimic biological Guanine crystals with superior optical … Guanine (symbol G or Gua) 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. The guanine nucleoside is called guanosine. With the formula C5H5N5O, guanine is a derivative of purine, … See more Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA. Guanine has two tautomeric forms, the major keto form (see figures) and rare enol form See more The first isolation of guanine was reported in 1844 by the German chemist Julius Bodo Unger [de] (1819–1885), who obtained it as a mineral formed from the excreta of sea birds, which is known as guano and which was used as a source of fertilizer; guanine … See more The word guanine derives from the Spanish loanword guano ("bird/bat droppings"), which itself is from the Quechua word wanu, meaning "dung".
