Beta-Oxidation

Definition

Beta-oxidation is the process where fatty acids are broken down in the cells to create energy.

Scientific / Technical Definition

Beta-oxidation is a metabolic process that involves the enzymatic removal of two-carbon units from the fatty acid chains at the beta carbon position. This process occurs within the mitochondria and results in the formation of acetyl-CoA, which then enters the citric acid cycle to produce ATP, the energy currency of cells.

Benefits

• Provides energy from fats during prolonged exercise.
• Supports efficient fat metabolism.
• Helps maintain energy levels when carbohydrates are not available.

Examples

• The breakdown of fatty acids during exercise.
• Utilization of stored fat for energy at rest.

Additional Information

• importance: Beta-oxidation is important for energy production, especially during periods of fasting, prolonged exercise, or carbohydrate limitation.
