Major pathways in the kidney
Gluconeogenesis
The main substrates in in kidney
Nonesterified fatty acids (NEFA),
lactate, glycerol, glucose
Major products exported by kidney
Glucose
Specialist enzymes in the kidney
Glycerol kinase (minimal amount),
Phosphoenolpyruvate carboxykinase
30% of gluconeogenesis in the body occurs here
Kidney
The enzyme for gluconeogenesis
Phosphoenolpyruvate carboxykinase
Why does hypoglycemia occur in patients with stage 4 chronic kidney disease?
Due to lessened activity of the gluconeogenic pathway
