Magnesium is sometimes denoted as "the overlooked cation" for although it is the second most abundant intracellular cation, the study of its homeostasis and regulation has long been neglected. However, at present it is evident that magnesium plays an important intracellular regulatory role. Magnesium transport systems can be divided into two principal categories: paracellular transport systems and transmembrane transport system. Paracellular pathway plays an important role in the intestinal and renal magnesium transports. The movement of magnesium across biological membranes is discussed from the perspectives of the secondary active transport and specific magnesium channels.
镁有时被称为“被忽视的阳离子”，因为尽管它是细胞内第二丰富的阳离子，但对其体内稳态和调节的研究长期以来一直被忽视。然而，目前很明显镁在细胞内发挥着重要的调节作用。镁转运系统可分为两大类：细胞旁转运系统和跨膜转运系统。细胞旁途径在肠道和肾脏的镁转运中起重要作用。从继发性主动转运和特定镁通道的角度讨论了镁跨生物膜的移动。
