核苷酸

 Nucleotides are formed from the condensation of nucleoside and a phosphate group. The nucleosides themselves are formed from a nucleobase (see below) and a sugar moiety which is either ribose (RNA) or 2’-deoxyribose (DNA). Nucleotides are the minimum structural units of DNA and RNA, and serve as important cofactors in metabolism.
