Essential Fructosuria

Picmonic
Essential fructosuria is an autosomal recessive metabolic disorder caused by a deficiency of the enzyme fructokinase, which catalyzes the degradation of fructose to fructose-1-phosphate in the liver. Unlike other defects in fructose metabolism, this deficiency causes a clinically benign condition characterized by incomplete metabolism of fructose and excretion of fructose in the urine without excess fructose entering cells. A diagnosis of essential fructosuria is typically made after a positive test for reducing substances in the urine. Because the disease is clinically benign, no treatment is indicated.

Fructokinase is the first enzyme involved in the degradation of fructose to fructose-1-phosphate.

Unlike other defects in fructose metabolism, essential fructosuria causes a clinically benign condition.

Fructose appears in blood and urine

Although fructose accumulates in blood and urine, it cannot enter cells and therefore causes a clinically benign condition. Fructose is excreted through the urine, causing a positive test for reducing substances.
