肝脏是维持体内血糖动态平衡的主要器官,进食后血糖升高或血浆胰岛素水平增加时,肝脏能摄取葡萄糖,经糖原合成酶和葡萄糖激酶催化合成糖原,以糖原形式储存在肝内.当饥饿时血糖降低或血浆胰岛素水平减少时,肝糖原则通过磷酸化酶催化分解为葡萄糖释放于血中,使血糖维持在恒定水 The liver is the main organ that maintains the homeostasis of blood glucose. When the blood glucose is increased or the plasma insulin level increases after eating, the liver can take in glucose, catalyze the synthesis of glycogen by glycogen synthase and glucokinase, and store it in the liver as glycogen. When the blood sugar when hungry or reduced plasma insulin levels, glycogen principle by phosphorylase catalytic decomposition of glucose released in the blood, so that blood glucose is maintained at a constant water
