Lanthanum belongs to the group of elements known as "lanthanons," which also includes cerium, europium, promethium, and thulium. It is the most electropositive element of the rare earth group, is uniformly trivalent, and is similar in its chemical properties to the alkaline earth elements. The effects of this element and its compounds on cellular systems are of considerable interest because of their increasing use in industry and as a substitute or antagonist for calcium in a variety of cellular reactions. Lanthanum is also being employed extensively in studying anatomical barriers, membrane structure, and subcellular transport systems, particularly the calcium pathway.
镧属于被称为“镧系元素”的元素组，该组还包括铈、铕、钷和铥。它是稀土族中电正性最强的元素，化合价始终为三价，其化学性质与碱土金属元素相似。由于该元素及其化合物在工业中的使用日益增加，并且在各种细胞反应中作为钙的替代物或拮抗剂，它们对细胞系统的影响备受关注。镧还被广泛用于研究解剖屏障、膜结构和亚细胞转运系统，尤其是钙通道。
