Adenine is a purine nitrogenous base found in DNA, RNA, and important biomolecules like ATP, NAD, and FAD, where it plays a crucial role in storing and transferring genetic information and cellular energy. It was first isolated in 1885 by the German chemist Albrecht Kossel, who later won the Nobel Prize for his work on nucleic acids, marking a foundational step in understanding the chemical composition of genetic material and the role of nucleobases in biology.
