Adenine /ˈædnn/ (A, Ade) is a nucleobase (a purine derivative) wi a variety of roles in biochemistry includin cellular respiration, in the form of baith the energy-rich adenosine triphosphate (ATP) an the cofactors nicotinamide adenine dinucleotide (NAD) an flavin adenine dinucleotide (FAD), an protein synthesis, as a chemical component o DNA an RNA.[2]
