一、戊糖磷酸途径 In most animal tissues, the major catabolic fate of glucose 6-phosphate is glycolytic breakdown to pyruvate, much of which is then oxidized via the citric acid cycle, ultimately leading to the formation of ATP
一、糖原的分解代谢 Glycogen in cells is first converted to Glc -6-P for oxidative degradation: 糖原磷酸化酶作用于糖原的非还原性末 端,经磷酸解作用,产生Glc-1-p 糖原磷酸化酶的辅基磷酸吡哆醛直接作 用于(a-1,4)糖苷键。 在距分支点四个糖单位处,糖原磷酸化 酶停止磷酸解作用
