'''半乳糖1-脱氢酶 (NADP<sup>+</sup>)'''（{{lang-en|galactose 1-dehydrogenase (NADP<sup>+</sup>)}}，[[EC编号|EC]] [http://enzyme.expasy.org/EC/1.1.1.120 1.1.1.120]{{Wayback|url=http://enzyme.expasy.org/EC/1.1.1.120 |date=20120806132532 }}），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]]：

:[[D-半乳糖|<small>D</small>-半乳糖]] + [[烟酰胺腺嘌呤二核苷酸磷酸|NADP<sup>+</sup>]] <math>\rightleftharpoons</math> [[半乳糖酸内酯|<small>D</small>-半乳糖酸内酯]] + NADPH + [[氢离子|H<sup>+</sup>]]

半乳糖1-脱氢酶 (NADP<sup>+</sup>)也能催化[[L-阿拉伯糖|<small>L</small>-阿拉伯糖]]、6-脱氧-<small>D</small>-半乳糖以及2-脱氧-<small>D</small>-半乳糖等发生反应。
