利用NMR技术研究极性二肽与金属离子间的相互作用
Study of the Interaction Between Polar Dipeptides and Metal Ions by NMR
摘要
Abstract
The interactions of 10 polar chain dipeptides( L-L configuration) with metal ions were exam-ined by NMR. These polar chain dipeptides exhibited a tremendous selectivity toward monovalent mental ion, showing a stoichiometric binding with 1∶1, and the association constants of dipeptides with Li+ were acquired. The results showed that L-Glu-L-Glu had stronger binding ability toward Li+ ions than other dipeptides, and suggested the electron-rich atoms in L-Glu-L-Glu molecular were favorable for the inter-action with metal ions. Furthermore, the interactions of divalent metal ions( Cu2+, Zn2+, Co2+) with 10 polar chain dipetieds were studied, which implied the interaction between them was carried out in two stages.关键词
