. . "Fructose is a 6-carbon polyhydroxyketone. When dissolved in solution fructose forms one of two ring structures - the 5-member ring |FRAME: Fructofuranose|and the 6-member ring |FRAME: D-Fructopyranose|. Mixtures at equilibrium contain 70% fructopyranose and 30% fructofuranose. A homopolymeric form of fructose is called |FRAME: Fructans|, and can be formed by β(2->1) or β(2->6) glycosidic bonds between fructose molecules."^^ . . . "D-fructose"^^ . "laevosan"^^ .
