Use：: Guanine is one of the two purines comprising the five nucleic acid bases. Much of the information regarding the general role of nucleic acid bases is covered in Adenine and Cytosine. Guanine gets its name from guano, from which it was first isolated in the 1840s. Albrecht Kossel (1853 1927) determined that guanine (as well as adenine, cytosine, thymine and uracil) was a component of nucleic acid in the last two decades of the 19th century. Similar to adenine, guanine combines with ribose to form a nucleoside. The nucleoside produced is guanosine, which in turn combines with one to three phosphoryls to yield the nucleotides guanosine monophosphate (GMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP), respectively. Guanine nucleotides play an important role in metabolism including the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) and carbohydrate metabolism.
