苹果酸脱氢酶（Malate Dehydrogenase，MDH）（EC 1.1.1.37）广泛存在于动物、植物、微生物和培养细胞中，线粒体中 MDH 是三羧酸循环（TCA）的关键酶之一，催化苹果酸形成草酰乙酸；相反，胞浆中MDH催化草酰乙酸形成苹果酸。草酰乙酸是重要的中间产物，连接多条重要的代谢途径。因此，MDH在细胞多种生理活动中扮演着重要的角色，包括线粒体的能量代谢、苹果酸-天冬氨酸穿梭系统、活性氧代谢和抗病性等。根据不同的辅酶特异性，MDH 分为 NAD-依赖的 MDH 和 NADP-依赖的 MDH。 本试剂盒检测原理是 NAD-MDH 催化 NADH 还原草酰乙酸生成苹果酸，导致340 nm处光吸收下降。
Malate Dehydrogenase (MDH) (EC 1.1.1.37) is widely present in animals, plants, microorganisms, and cultured cells. Within mitochondria, MDH serves as a key enzyme in the tricarboxylic acid (TCA) cycle, catalyzing the conversion of malate to oxaloacetate. Conversely, cytosolic MDH catalyzes the formation of malate from oxaloacetate. Oxaloacetate is a crucial intermediate that links multiple significant metabolic pathways. Consequently, MDH plays a vital role in various cellular physiological processes, including mitochondrial energy metabolism, the malate-aspartate shuttle system, reactive oxygen species metabolism, and disease resistance. Based on coenzyme specificity, MDH is classified into NAD-dependent MDH and NADP-dependent MDH. The detection principle of this kit is that NAD-MDH catalyzes the reduction of oxaloacetate by NADH to produce malate, resulting in a decrease in light absorption at 340 nm.
