adeniinidinucleotide

Adenine dinucleotide refers to a molecule composed of two adenine bases linked together. In biological contexts, this typically refers to a specific type of molecule where the adenine bases are connected via a phosphate linkage. One of the most biologically relevant examples is adenosine diphosphate (ADP) and adenosine triphosphate (ATP), which are crucial for energy transfer in all living organisms. These molecules are nucleoside diphosphates and triphosphates, respectively, and contain adenine. While the term "adenine dinucleotide" can broadly describe any molecule with two adenine bases, it is often used informally to allude to the components of these high-energy phosphate compounds. The structure and function of these molecules are central to cellular metabolism and are extensively studied in biochemistry and molecular biology.
