Also known as levulose or fruit sugar, fructose (C6H12O6) is widely distributed in plants. It is one of the three most important blood sugars along with glucose and galactose, and is used to produced energy by a process called glycolysis, which takes place in the liver. Fructose is important in the diet of diabetics (see diabetes mellitus) since, unlike glucose, fructose metabolism is not dependent on insulin.
Found in foods such as honey, berries, melons, figs, and and some root vegetables (e.g., beets, sweet potatoes, and parsnips) fructose is the sweetest naturally occurring sugar.
Fructosia (also called levulosuria) is the presence of fructose in the urine.
