/* Purine Nitrogenous bases */
===Guanine===
Guanine, a two-ring molecular structure, and is derived from the two-ring parent molecule purine. Guanine is comprised a six-carbon pyrimidine ring fused with a five-carbon imidazole ring with a carbonyl and amine attached to the six-carbon ring. Being unsaturated, the bicyclic molecule is planar. The guanine nucleoside is called guanosine and lacks only a phosphate to form a nucleotide. Guanosine can be phosphorylated with phosphoric acid groups, creating Guanosine monophosphate (GMP), Guanosine diphosphate (GDP) or Guanosine triphosphate (GTP).
