https://usmleqa.com/?p=28313
Question: What is Essential fructosuria?
Answer: Essential fructosuria is a benign, asymptomatic condition that involves a defect in fructokinase. It is an autosomal recessive condition.Question: What is the cause of Essential fructosuria?
Answer: Essential fructosuria is caused by a defect in fructokinase.Question: How does fructokinase deficiency affect fructose metabolism?
Answer: Fructokinase deficiency means that fructose is not trapped in cells, and hexokinase becomes the primary pathway for converting fructose to fructose-6-phosphate.Question: What are the symptoms of Essential fructosuria?
Answer: The symptoms of Essential fructosuria include the appearance of fructose in blood and urine.Question: How do disorders of fructose metabolism compare to analogous disorders of galactose metabolism?
Answer: Disorders of fructose metabolism cause milder symptoms than analogous disorders of galactose metabolism. Question: Is Essential fructosuria a serious condition?
Answer: No, Essential fructosuria is a benign and asymptomatic condition.Question: What type of genetic inheritance pattern does Essential fructosuria follow?
Answer: Essential fructosuria is an autosomal recessive condition.Question: What is the role of hexokinase in Essential fructosuria?
Answer: In Essential fructosuria, hexokinase becomes the primary pathway for converting fructose to fructose-6-phosphate due to fructokinase deficiency.Question: How does the presence of fructose in blood and urine indicate Essential fructosuria?
Answer: The presence of fructose in blood and urine is a symptom of Essential fructosuria, indicating the deficiency of fructokinase.Question: Are disorders of fructose metabolism more severe than disorders of galactose metabolism?
Answer: No, disorders of fructose metabolism cause milder symptoms compared to analogous disorders of galactose metabolism. Question: Is fructokinase deficiency a common condition?
Answer: Information about the prevalence of fructokinase deficiency is not readily available.Question: How does Essential fructosuria affect fructose metabolism?
Answer: Essential fructosuria affects fructose metabolism by causing a deficiency in fructokinase, which leads to fructose not being trapped in cells and hexokinase becoming the primary pathway for converting fructose to fructose-6-phosphate.Question: Can Essential fructosuria cause any serious health problems?
Answer: No, Essential fructosuria is a benign and asymptomatic condition and does not cause any serious health problems.Question: What is the relationship between fructokinase and fructose metabolism?
Answer: Fructokinase is an enzyme involved in fructose metabolism. A deficiency in fructokinase leads to alterations in the metabolism of fructose.Question: Are there any other disorders related to fructose metabolism?
Answer: Yes, there are other disorders related to fructose metabolism, but Essential fructosuria is one specific example.tab
