The beta (β) Fructose molecule - rotatable in 3 dimensions. Fructose (fruit sugar) is a monosaccharide - formula C 6 H 12 O 6. It shares the same empirical formula with other 6-carbon (hexose) sugars such as glucose and galactose.

Although fructose is a hexose (6 carbon sugar), it generally exists as a 5-member hemiketal ring (a furanose). This structure is responsible for the long metabolic pathway and high reactivity compared to glucose (See below structure -note: hydrogens not shown)
You need to know the structure of the three main monosaccharides: glucose, fructose, and galactose. Learn to draw these in preparation of your exams. More importantly, you also need to know the isomers of glucose, alpha and beta glucose (note that the groups on the right are reversed).
