The removal of one or more electrons from a fatty acid, with or without the concomitant removal of a proton or protons, by reaction with an electron-accepting substance, by addition of oxygen or by removal of hydrogen. A fatty acid oxidation process that results in the complete oxidation of a long-chain fatty acid. Fatty acid beta-oxidation begins with the addition of coenzyme A to a fatty acid, and occurs by successive cycles of reactions during each of which the fatty acid is shortened by a two-carbon fragment removed as acetyl coenzyme A; the cycle continues until only two or three carbons remain (as acetyl-CoA or propionyl-CoA respectively). A fatty acid beta-oxidation pathway by which fatty acids having cis-double bonds on even-numbered carbons are degraded. In this pathway, the intermediate 2,4-dienoyl-CoA is converted to trans-2-enoyl-CoA by 2,4-dienoyl-CoA reductase and delta3-delta2-enoyl-CoA isomerase; trans-2-enoyl-CoA returns to the core beta-oxidation pathway for further degradation. Fatty acid beta-oxidation begins with the addition of coenzyme A to a fatty acid, and ends when only two or three carbons remain (as acetyl-CoA or propionyl-CoA respectively). A fatty acid beta-oxidation pathway by which fatty acids having cis-double bonds on even-numbered carbons are degraded. In this pathway, the intermediate 2,4-dienoyl-CoA is converted to cis-2-enoyl-CoA through one more cycle of the core beta-oxidation pathway. Cis-2-enoyl-CoA cannot be completely degraded via the core beta-oxidation pathway because hydratation of cis-2-enoyl-CoA yields D-3-hydroxyacyl-CoA, which is not a substrate for 3-hydroxylacyl-CoA dehydrogenase. Cis-2-enoyl-CoA must enter the so-called epimerase pathway, which involves converting D-3-hydroxyacyl-CoA to L-3-hydroxyacyl-CoA by 3-hydroxylacyl-CoA epimerase or by two stereo-specific enoyl-CoA hydratases. L-3-hydroxyacyl-CoA then returns to the core beta-oxidation pathway. Fatty acid beta-oxidation begins with the addition of coenzyme A to a fatty acid, and ends when only two or three carbons remain (as acetyl-CoA or propionyl-CoA respectively). A fatty acid beta-oxidation pathway by which fatty acids having cis-double bonds on even-numbered carbons are degraded. Fatty acid beta-oxidation begins with the addition of coenzyme A to a fatty acid, and ends when only two or three carbons remain (as acetyl-CoA or propionyl-CoA respectively). The chemical reactions and pathways resulting in the breakdown of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes.
