Abstract
Phosphorus NMR spectra were recorded for complexes of Na2ATP and Li4ATP with varying concentrations of magnesium, calcium and lithium. Each ion caused a shift in the phosphorus resonances, usually downfield, and a decrease in the 31P-31P coupling constant. The sodium ATP formed a 1:1 complex with each ion and a 1:2, ATP:Mg complex with magnesium whilst lithium ATP gave evidence to suggest the formation of bis(nucleotide) complexes.
摘要
记录了不同浓度的镁、钙和锂与 Na2ATP 和 Li4ATP 形成的配合物的磷核磁共振光谱。每种离子都会导致磷共振发生位移，通常是向低场位移，并且 31P-31P 耦合常数降低。钠 ATP 与每种离子形成 1:1 的配合物，与镁形成 1:2 的 ATP:Mg 配合物，而锂 ATP 则有证据表明形成了双（核苷酸）配合物。
