Adenine /ˈædɨnɨn/ (A Ade) is a nucleobase (a purine derivative) with a variety of roles in biochemistry including cellular respiration in the form of both the energy-rich adenosine triphosphate (ATP) and the cofactors nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) and protein synthesis as a chemical component of DNA and RNA. The shape of adenine is complementary to either thymine in DNA or uracil in RNA.
