'''<small>D</small>-半乳糖1-脱氢酶'''（{{lang-en|<small>D</small>-galactose 1-dehydrogenase}}，[[EC编号|EC]] [http://enzyme.expasy.org/EC/1.1.1.48 1.1.1.48]{{Wayback|url=http://enzyme.expasy.org/EC/1.1.1.48 |date=20120418154541 }}）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|NAD<sup>+</sup>]] <math>\rightleftharpoons</math> <small>D</small>-[[半乳糖酸]]-1,4-[[内酯]] + NADH + [[氢离子|H<sup>+</sup>]]

<small>D</small>-半乳糖1-脱氢酶主要参与[[半乳糖]]的[[代谢]]过程，一些[[细菌]]在需要依赖半乳糖生长时就会利用这种酶。
