'''半乳糖醇2-脱氢酶'''（{{lang-en|galactitol 2-dehydrogenase}}，[[EC编号|EC]] [http://enzyme.expasy.org/EC/1.1.1.16 1.1.1.16]{{Wayback|url=http://enzyme.expasy.org/EC/1.1.1.16 |date=20120412173154 }}）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]]：

:[[半乳糖醇]] + [[烟酰胺腺嘌呤二核苷酸|NAD<sup>+</sup>]] <math>\rightleftharpoons</math> [[D-塔格糖]] + NADH + [[氢离子|H<sup>+</sup>]]

半乳糖醇2-脱氢酶主要参与[[半乳糖]]的[[代谢]]过程。这种酶还能将拥有与[[伯羟基]]相邻的L-[[苏式构型]]（L-''threo''-configuration）的[[糖醛]]转化为对应的[[糖类]]。
