Fatty acids are an important source of energy. They are stored as triglycerides or fats. Fatty acid catabolism is a metabolic process by which our body utilises the energy stored in triglycerides. One gram of fatty acid yields approximately 9 kcal of energy. The fat present in our food is digested by lipase secreted by the pancreas in the duodenum. Triglycerides are converted to fatty acid and glycerol. Long-chain fatty acids undergo 𝜷-oxidation in the mitochondrial matrix, forming acetyl CoA.
