Le guanina es un del cinque bases nitrogenate que forma parte del acidos nucleic (ADN e ARN) e in le codice genetic se representa con le character G. Le altere quatro bases son le adenina, le cytosina, le thymina e le uracil. Forma le nucleosides guanosina (Guo) e desoxyguanosina (dGuo), e le nucleotides guanilate (GMP) e desoxyguanilate (dGMP). Le guanina semper es in par in le ADN con le cytosina mediante tres ligamines de hydrogeno.
