WebMay 6, 2024 · A nitrogenous base is an organic molecule that contains the element nitrogen and acts as a base in chemical reactions. The basic property derives from the lone electron pair on the nitrogen atom. The nitrogen bases are also called nucleobases because they play a major role as building blocks of the nucleic acids deoxyribonucleic acid ( DNA) and ... WebIn the Brønsted–Lowry definition of acids and bases, a conjugate acid–base pair consists of two substances that differ only by the presence of a proton (H⁺). A conjugate acid is formed when a proton is added to a base, and a conjugate base is formed when a proton is removed from an acid. Created by Yuki Jung. Sort by:
