L-半乳糖脱氢酶(EC 1.1.1.316，L-galactose dehydrogenase,GalDH)是植物合成抗坏血酸Vc的重要酶之一，L-半乳糖脱氢酶在C1位直接氧化L-半乳糖生成Vc合成的直接底物—L-半乳糖-1,4-内酯，同时将NAD⁺还原为NADH。 本试剂盒提供一种简单，灵敏，快速的测定方法：该酶促过程产生的NADH与特异显色剂反应产生在450nm处有最大吸收峰的有色物质，通过检测450nm处的增加速率，进而计算出GalDH酶活性大小。
L-galactose dehydrogenase (GalDH, EC 1.1.1.316) is one of the key enzymes involved in the synthesis of ascorbic acid (vitamin C) in plants. It directly oxidizes L-galactose at the C1 position to produce L-galactono-1,4-lactone, the immediate precursor for ascorbic acid synthesis, while simultaneously reducing NAD⁺ to NADH. This kit provides a simple, sensitive, and rapid assay: NADH generated during this enzymatic reaction reacts with a specific chromogenic agent to form a colored product with a maximum absorption peak at 450 nm. The activity of GalDH is calculated by measuring the rate of increase in absorbance at this wavelength.
