There are several congenital disorders of fructose metabolism resulting from a variety of enzyme deficiencies.  These patients have difficulty using fructose for a variety of reasons, of course depending on the specific deficient gene product.  Fructose is regularly consumed by humans because of their omnivorous diet that includes fruits (…and other sweets).    FBPase-1 deficiency is one example of a deficiency that leads to a disorder of fructose metabolism.   Predict whether or not you think FBPase-1 deficient patients will have depletion of inorganic phosphate in cells during fasting.  Why is depletion of inorganic phosphate so deleterious to cells
