This pathway depicts several metabolic pathways involved in ketogenic diet treatment.
In hepatocytes in the liver, fatty acids (FAs) are normally transformed into acetyl-CoA, which can then enters the TCA (Krebs) cycle for energy production.
However, when FA levels are to high for the TCA cycle to be utilized completely, acetyl-CoA is used in ketogenesis and ketolysis.
These processes are a complex process of transporter proteins and several other (mitochondrial) pathways [https://www.ncbi.nlm.nih.gov/books/NBK98219/figure/masino.f1/].
