摘要: 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.

关键词: 稀土, L-氨基酸, 旋光度

Abstract: The influence of ionic strength, acidity and concentration of rare earth on the specific rotation of L-methionine and L-histidine were investigated. The results of the specific rotation determined illustrate that the configuration of L-methionine and L-histidine do not change after the interaction with rare earthions.

Key words: Rare earth, L-Amino acids, Specific rotation
