Betaoxidation is the catabolic process by which fatty acid molecules are broken down[1] in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetylCoA, which enters the citric acid cycle, and NADH and FADH2, which are coenzymes used in the electron transport chain. It is named as such because the beta carbon of the fatty acid undergoes oxidation to a carbonyl group. Betaoxidation is primarily facilitated by the mitochondrial trifunctional protein, an enzyme complex associated with the inner mitochondrial membrane, although some fatty acids are oxidized in peroxisomes. Beta oxidation also generates large amounts of water which is essential for animals such as camels that often have limited access to water.
