Fructose is more commonly found together with glucose and sucrose in honey and fruit juices. Fructose, along with glucose are the monosaccharides found in disaccharide, sucrose. Fructose is classified as a monosaccharide, the most important ketose sugar, a hexose, and is a reducing sugar.

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.
Fructose is identified as a five-membered ring having six-carbon, a hexose, whereas glucose is a six-membered ring with a –OH group on the carbon at the 4 th position in a down projection. Molecular and Structure Formula of Fructose. Fructose is a levorotatory monosaccharide, which means it rotates the plane-polarised light in the left direction.
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).
30 Σεπ 2024 · fructose, a member of a group of carbohydrates known as simple sugars, or monosaccharides. Fructose, along with glucose, occurs in fruits, honey, and syrups; it also occurs in certain vegetables. It is a component, along with glucose, of the disaccharide sucrose, or common table sugar.
