| Biochem/physiol Actions: | Cytosine (C) is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). |
| Biochem/physiol Actions: | Cytosine is a pyrimidine, which forms three hydrogen bonds to base pair with guanine. It forms a nucleotide cytidine, that is phosphorylated to cytidine 5′ monophosphate (CMP), cytidine 5′ diphosphate (CDP) and cytidine 5′ triphosphate (CTP). |
