Fatty acids β the physiological significance of oxidation.

. Namefatty acids β - oxidation is the main way to break down fatty acids in the body, fatty acid oxidation can supply the body needs a large amount of energy, to 18 carbon atoms of the saturated fatty acid stingrays, for example, its β-The total reaction of oxidation is: CH3 (CH2) 15COSCoA plus 8NAD plus CoASH plus 8H2O- →9CH3COSCoA plus 8FADH 2 plus 8NADH plus 8H plus 8 molecule FADH2 provides 8×2 plus 16 molecule ATP, 8 molecule NADH plus H plus provides 8×3 plus 24 molecule ATP, 9 molecule acetylCoA fully oxidized to provide 9×12 x 108 molecules ATP, so a 1 g of molecular stat acid fully oxidized to produce CO2 and H2O, a total of 148 grams of molecular ATP. The active process of stat acid consumes 2 grams of molecular ATP, so a 1 g of molecular stat acid can be fully oxidized to produce a net 146 grams of molecular ATP. A glucose molecule is fully oxidized to produce 38 molecule ATP. Three grams of molecular glucose contains the same number of carbon atoms as a 1 g of molecular stat acid, which provides 114 grams of molecular ATP, and 146 grams of molecular ATP. It can be seen that fatty acids provide more energy when the number of carbon atoms is the same. About 40% of the energy released by fatty acid oxidation is the body's use of synthetic high-energy
compound
, the remaining 60% is released in the form of heat, thermal efficiency of 40%, indicating that the human body can very effectively use the energy provided by fatty acid oxidation.fatty acids β-oxidation is also the transformation process of fatty acids, the length of the fatty acid chain required by the human body is different, through β-oxidation can be long-chain fatty acids to transform the growth of suitable fatty acids, for the body's metabolism needs.fatty acids β - acetylCoA produced during the oxidation process is a very important intermediate compound, acetylCoA in addition to entering the triacetic acid cycle oxidation energy supply, but also a number of important compounds synthesis of raw materials, such as ketones, cholesterol and steroid compounds.
