rate-limiting

The formation of ADP-Glucose is a rate-limiting step during starch synthesis. This equilibrium is directly regulated by the supplement of ATP as a substrate, which in turn definite influences the character of plant starch.

ADP-葡萄糖（ADPG）的形成是淀粉合成的限速步骤，该反应平衡受底物ATP供给水平调控，最终影响植物淀粉性状。

Our calculations indicated that the total reaction is stepwise and exothermic, and that the rate-limiting step is to overcome the barrier ( 9.36 kcal/ mol) in the second step.

计算结果表明，整个反应是一个放热过程，第二步反应是整个反应过程的决速步骤，反应能垒为9.36kcal/mol。

The translocation of cholesterol from the out to the inner mitochondrial membrane is a rate-limiting step that requires steroidogenic acute regulator protein ( StAR) synthesis de novo in steroidogenesis.

在类固醇激素的合成过程中，胆固醇由线粒体外膜到内膜转运的过程是类固醇激素合成的限速步骤，这一步骤必需有类固醇激素灵敏调节蛋白（StAR）的从头合成才能完成。
