Cytosine is an aminopyrimidine that is pyrimidin-2-one having the amino group located at position 4. It has a role as a human metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is a pyrimidine nucleobase, a pyrimidone and an aminopyrimidine.

Cytosine (/ ˈsaɪtəˌsiːn, - ˌziːn, - ˌsɪn / [2][3]) (symbol C or Cyt) is one of the four nucleotide bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2).
