Adenine /ËaedÉ¨nÉ¨n/ (ËÃ¦dÉ¨nÉ¨n, 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). faddenine is one of the two purine nucleobases (the other being guanine) used in forming nucleotides of the nucleic acids. In DNA, adenine binds to thymine via two hydrogen bonds to assist in stabilizing the nucleic acid structures. In RNA, which is used for protein synthesis, adenine binds to uracil.
