Disease Roles
Fatty Acid Mitochondrial Transport System (Carnitine Shuttle) Overview
The fatty acid mitochondrial transport system, commonly known as the carnitine shuttle, is a critical biochemical pathway that enables the transport of long-chain fatty acids from the cytosol into the mitochondrial matrix for β-oxidation and subsequent energy production. It involves CPT I, carnitine-acylcarnitine translocase, and CPT II.
Mechanism of Action
The carnitine shuttle transports long-chain fatty acids from the cytosol into the mitochondrial matrix for beta-oxidation.
Biological Functions
Fatty Acid Transport
Beta-Oxidation
Energy Production
Lipid Metabolism
Disease Associations
Carnitine Deficiency
Fatty Acid Oxidation Disorders
Hypoketotic Hypoglycemia
Muscle Weakness
Myopathy
Rhabdomyolysis
Safety Considerations
- Inhibition of CPT I can lead to accumulation of fatty acids in the cytosol.
- Defects in any component can lead to metabolic disorders.
Interacting Drugs
