Webb2 okt. 2024 · Ribose has five conformational isomers or conformers, each of which can react with a nucleobase. In life, however, only the β-furanose form of ribose is used. Curiously, when a nucleobase reacts with ribose in an aqueous solution, only a small amount of nucleoside with a β-ribofuranose component is detectable in the total products.
