Study Notes
Lactose Intolerance
- Lactose intolerance is the inability to digest lactose, a sugar found in milk.
Ketogenesis and Ketolysis
- There are three main ketone bodies: acetone, β-hydroxybutyrate, and acetoacetate.
- All three main ketone bodies are formed from Acetyl CoA.
- Acetyl CoA can be transferred between cells.
- Ketogenic amino acids are amino acids that can be converted to ketone bodies.
Ketogenesis
- Ketogenesis occurs in liver cells.
- Three molecules of acetyl CoA form 3-hydroxy-3-methylglutaryl (HMG-CoA), which then forms acetoacetate and β-hydroxybutyrate (BtHB).
- Ketone bodies formed in the liver cell escape into the bloodstream and are transferred to extrahepatic cells.
Ketolysis
- Ketolysis occurs in extrahepatic cells.
- Ketone bodies are broken down in ketolysis to provide energy.
The Function of Ketone Bodies
- Cells with excess acetyl CoA can transfer it to cells with less acetyl CoA.
- Ketone bodies serve as an energy source for cells.
