Lipid Oxidation

Meaning

Lipid oxidation is the metabolic process where fatty acids are broken down to generate acetyl-CoA, which subsequently enters the Krebs cycle to produce cellular energy in the form of ATP. This process, also known as beta-oxidation, is fundamentally important for energy metabolism, particularly during periods of fasting or prolonged exercise. Hormonal signals, notably those from the thyroid and adrenal glands, tightly regulate the rate of lipid oxidation, directly impacting body composition and energy expenditure.
