Structural formula: {0} (CAS {1})

Guanine is a 2-aminopurine carrying a 6-oxo substituent. It has a role as a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a human metabolite and an algal metabolite. It is a member of 2-aminopurines, an oxopurine and a purine nucleobase. It derives from a hydride of a 9H-purine.
