| 摘 要： | 利用放射线检测器和分光光度计,对肉鸭肝脏中参与脂肪酸合成的酶类:乙酰辅酶-A羧化酶,脂肪酸合成酶,NADP-苹果酸脱氢酶,葡萄糖-6-磷酸脱氢酶等酶的活性进行了测试分析.结果表明,肉鸭肝脏的各种脂肪酸代谢酶类的活性表现为:42日龄比21日龄的显著增加,显示随着日龄的增加,鸭肝脏合成脂肪的能力也显著增强.鸡的肝脏进行脂肪酸合成所必需的NADPH主要是由NADP-苹果酸脱氢酶参与的丙酮酸-苹果酸途径提供.与此相比,鸭的葡萄糖-6-磷酸脱氢酶的活性非常高,显示鸭的脂肪酸合成途径与鸡不同,脂肪酸的合成不仅仅有丙酮酸-苹果酸途径参与,戊糖磷酸循环也起到关键性的作用.

| Abstract: | This paper tested the fatty acid synthetases'activity, and the result showed that the fatty acid metabolic enzymes of the 42-day meat-type ducks were much higher than the 21-day group.The activity of Gucose-(6-phosphate) dehydrogenase was quite high,which indicated its fatty acid synthetic method was different from that of the chicken:the fatty acid synthesis included not only the pyruvate-malate pathway;also the pentose phosphate pathway played a key role. |
