'''<small>D</small>-木酮糖还原酶'''（{{lang-en|<small>D</small>-xylulose reductase}}，[[EC编号|EC]] [http://enzyme.expasy.org/EC/1.1.1.9 1.1.1.9]{{Wayback|url=http://enzyme.expasy.org/EC/1.1.1.9 |date=20120120142255 }}）是一种以[[烟酰胺腺嘌呤二核苷酸|NAD<sup>+</sup>]]或[[烟酰胺腺嘌呤二核苷酸磷酸|NADP<sup>+</sup>]]为[[受体 (生物化学)|受体]]、作用于[[供体]][[次甲基|CH]]-[[羟基|OH]][[基团]]上的[[氧化还原酶]]。这种[[酶]]能[[催化]]以下[[酶促反应]]：

:[[木糖醇]] + [[烟酰胺腺嘌呤二核苷酸|NAD<sup>+</sup>]] <math>\rightleftharpoons</math> [[D-木酮糖|<small>D</small>-木酮糖]] + NADH + [[氢离子|H<sup>+</sup>]]

<small>D</small>-木酮糖还原酶也可以作为[[L-赤藻酮糖|<small>L</small>-赤藻酮糖]]，它主要参与[[戊糖]]和[[葡萄糖醛酸]]之间的转化过程。
