fructofuranose

Fructofuranose is a chemical compound that is a form of fructose, a simple sugar. Fructose, also known as fruit sugar or levulose, is sweeter and more soluble than glucose. It is found naturally in fruits, honey, and syrups, and is a component of common table sugar (sucrose).12

Fructose can exist in a molecular form called a furanose, which possesses a tetrahydrofuran ring system. This furanose form of fructose is specifically referred to as fructofuranose. Tetrahydrofuran is a five-membered heterocyclic aromatic ring containing one oxygen atom and four carbon atoms. Phosphate derivatives of fructose are important in carbohydrate metabolism.342
