1H NMR analyses of individual α-amino acids in their mixture were simultaneously conducted in the presence of Sm-(pdtaâd8) in water: high regularity, promising for direct simultaneous determination of absolute configurations of each α-amino acids in peptide hydrolysate mixtures, was observed between absolute configuration and the induced shifts.
在水中加入 Sm-(pdtaâd8)的情况下,同时对δ-氨基酸混合物中的各个δ-氨基酸进行了 1H NMR 分析:观察到绝对构型与诱导位移之间具有高度的规律性,有望直接同时测定肽水解物混合物中各个δ-氨基酸的绝对构型。
