Flies offer insight into human metabolic disease

Galactosemia is a metabolic disease resulting from an inherited defect that prevents the proper metabolism of galactose, a sugar commonly found in dairy products, like milk. Exposure of affected people to galactose, can damage most of their organ systems and can be fatal. The ability to study the disease is limited by a lack of animal models.
