Cell with -galactose, metabolic

Hereditary fructose intolerance is caused by an autosomal recessive hereditary defect of the enzyme fructose-l-phosphate aldolase. Whenever fructose is supplied, severe hypoglycaemia and functional disorders occur in the liver, kidneys and CNS. The prevalence is estimated at 1 20,000 births. As with galactose intolerance, the gene which codes aldolase B is also localized on chromosome 9. This enzyme defect causes fructose-l-phosphate to accumulate in the liver and tissue. The cleavage of fructose-1,6-biphosphate is only slightly compromised since the enzymes aldolase A and C are available for this process. The consumption of phosphate and ATP in the tissue results in various functional disorders (i.) inhibition of gluconeogenesis in the liver and kidneys, (2.) increase in lactate in the serum with metabolic acidosis, (3.) decrease in protein synthesis in the liver, and (4.) functional disorders of the proximal tubular cells with development of Fanconi s syndrome, (s. pp 593, 594) (193, 194, 196, 198)...
