前言胎儿经分娩脱离母体后,在独立生活环境中的适应过程称为新生儿期。此期代谢是由合成代谢转为分解代谢的激烈变化阶段。因能量需要增加,代谢系统必须调整适应。本文报道在此过程的能量平衡中糖、脂肪、蛋白质代谢系统的变化。一、能量代谢的适应线粒体中氧呼吸和产生化学能量的结构,是能量代谢的基础。动物实验得知,大鼠肝线粒体的呼吸能在胎仔期ADP(腺苷二磷酸)/O_2(氧)比值为1.13;呼吸调节 Preface The fetus after childbirth from the mother, the adaptation process in an independent living environment is called the neonatal period. This period of metabolism is from anabolism to catabolism in the fierce phase of change. Due to the increased need for energy, the metabolic system must be adapted. This article reports on changes in the energy balance of sugar, fat, and protein metabolism during this process. First, the energy metabolism to adapt to mitochondrial oxygen respiration and chemical energy structure, is the basis of energy metabolism. Animal experiments showed that rat liver mitochondrial respiration energy in the fetal ADP (adenosine diphosphate) / O 2 (oxygen) ratio of 1.13; respiratory regulation
