/fruk"tohs, frook"-, froohk"-/, n.
Chem., Pharm. a yellowish to white, crystalline, water-soluble, levorotatory ketose sugar, C6H12O6, sweeter than sucrose, occurring in invert sugar, honey, and a great many fruits: used in foodstuffs and in medicine chiefly in solution as an intravenous nutrient. Also called levulose, fruit sugar.

* * *

Organic compound, one of the simple sugars (monosaccharides), chemical formula C6H12O6.

It occurs in fruits, honey, syrups (especially corn syrup), and certain vegetables, usually along with its isomer glucose. Fructose and glucose are the components of the disaccharide sucrose (table sugar); hydrolysis of sucrose yields invert sugar, a 50:50 mixture of fructose and glucose. The sweetest of the common sugars, fructose is used in foods and medicines.

      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. Phosphate derivatives of fructose (e.g., fructose-1-phosphate, fructose-1,6-diphosphate) are important in the metabolism of carbohydrates.
