The succinyl-CoA can then enter the TCA cycle for further oxidation. The oxidation of unsaturated fatty acids is essentially the same process as for saturated fats, except when a double bond is encountered. In such a case, the bond is isomerized by a specific enoyl-CoA isomerase plump your pucker and oxidation continues. In the case of linoleate, the presence of the D-12 unsaturation results in plump your pucker the formation of a dienoyl-CoA during oxidation. This molecule is the substrate for an additional oxidizing enzyme, the NADPH requiring 2,4-dienoyl-CoA reductase. |

| The acetyl-CoA--- the end product of each round of b-oxidation--- then enters the TCA cycle, where coconut fatty acid it is further oxidized to CO2 with the concomitant generation of three moles of NADH, one mole of FADH2 and one mole of ATP. The NADH and FADH2 generated during the fat oxidation and acetyl-CoA oxidation in the TCA cycle then can enter the respiratory pathway for the production of ATP. The oxidation of fatty acids yields significantly more energy per carbon atom than does the oxidation of carbohydrates. The net result of the oxidation of one coconut fatty acid mole of oleic acid (an coconut fatty acid 18-carbon fatty acid) will be 146 moles of ATP (2 mole equivalents are used during the activation of the fatty acid), as compared with 114 moles from an equivalent number of glucose carbon atoms. Alternative Oxidation Pathways The majority of natural lipids contain an even number of carbon atoms. A small proportion that contain odd numbers; upon complete b-oxidation, these yield acetyl-CoA units plus a single mole of propionyl-CoA. |
