Carbohydrate metabolism

Most important ones: glucose, galactose, and fructose

 

3 parts of carbohydrate metabolism

  1. Glycolysis
    (aka Embden-Meyerhof pathway)
  2. Citric acid cycle
    (aka Krebs cycle)
  3. Oxidative phophorylation

Other pathways in carbohydrate metabolism

 

Other notes on carbohydrate metabolism

Fructose

Fructose is converted to:

Fructose 6-phosphate can then be converted to:

 

Fructose 2,6-phosphate

[WG21:p295]

Potent regulator of hepatic gluconeogenesis

When level of F2,6P is high
-> Conversion of F6P to F1,6P increased
-> Increased glycolysis

When level of F2,6P is low
-> Conversion of F1,6P to F6P increased
-> Increased gluconeogenesis

 

Catecholamine
