Study Notes
Fructose Metabolism
- The major rate-limiting step in glycolysis that fructose bypasses is phosphofructokinase-1.
Liver Steatosis
- The potential cause of liver steatosis due to fructose metabolism is the uncontrolled generation of acetyl-CoA, which can lead to excessive fat synthesis.
Fat Synthesis
- Acetyl-CoA is a precursor to fat synthesis.
Uncontrolled Fructose Metabolism
- The consequence of fructose being metabolized without any control to acetyl-CoA is the unregulated production of fat, leading to liver steatosis and other metabolic disorders.
Fructokinase Deficiency
- Fructokinase deficiency, also known as essential fructosuria, results in the inability to metabolize fructose, leading to its excretion in the urine.
Fructose Metabolism Pathway
- Fructose is directly cleaved without going through the phosphofructokinase-1 step, causing the metabolization of acetyl-CoA without any control.
Liver Condition
- The term for the condition where there is an accumulation of fat in the liver is liver steatosis.
Fructokinase Enzyme
- The term for the enzyme that converts fructose to fructose 1 phosphate is fructokinase.
