稀土在农林牧业和医学方面应用的不断扩大，导致稀土通过多种途径进入人体．为此，有必要了解稀土对生物体的近期和远期效应［１］．研究稀土与氨基酸的相互作用将为探索稀土在生物体内的代谢及其生物效应提供基础．近２０年来，稀土－氨基酸配合物的研究一直为人们所重视... Rare earths in agriculture, forestry, animal husbandry and medical applications continue to expand, resulting in rare earth into the body through a variety of ways. To this end, it is necessary to understand the short-term and long-term effects of rare earth on organisms [1]. Studying the interaction between rare earths and amino acids will provide a basis for exploring the metabolism of rare earths in vivo and their biological effects. In the past 20 years, the research of rare earth-amino acid complex has been paid attention to by people.
