Effect of insulin on the oxidation of carbons-1,4 and -2,3 of succinate and their incorporation into protein were studied in isolated rat hepatocytes and diaphragm muscle pieces. Oxidation of carbons-2,3 of succinate and their incorporation into hepatocyte protein were stimulated significantly by insulin. Insulin had only a trivial effect on 14CO2 formation from the carboxyl carbons of succinate. These data suggest that insulin affects only those carbons of succinate that are metabolized in the intramitochondrial Krebs cycle.
在分离的大鼠肝细胞和膈肌肌片中研究了胰岛素对琥珀酸碳-1、4和碳-2、3的氧化及其掺入蛋白质的影响。胰岛素显著刺激了琥珀酸碳-2、3的氧化及其掺入肝细胞蛋白质的过程。胰岛素对琥珀酸羧基碳生成14CO2的影响微不足道。这些数据表明,胰岛素仅影响在线粒体内三羧酸循环中代谢的琥珀酸的那些碳原子。
