Definition

Noun: A rare, typically benign metabolic condition characterized by the abnormal presence of fructose (levulose) in the urine. It is caused by a deficiency in the enzyme fructokinase, which prevents the normal metabolism of fructose.

Usage

The term is used in medical and biochemical contexts to describe a specific, usually asymptomatic, diagnostic finding. * The pediatrician noted that the infant's fructosuria was an incidental finding during routine screening. * Fructosuria is distinguished from more serious fructose metabolism disorders by its lack of clinical symptoms.

Advanced Usage

• Essential fructosuria: This is the full medical term for the specific benign condition, differentiating it from other causes of fructose in the urine.
