摘要

用电位法测定了外聚苏氨酸(Thr, allo-Thr)和异亮氨酸(Ile, allo-Ile)的酸解常数及其与Co2+和Cu2+配合物的稳定性常数。天然端尖形成的络合物比同种异体更稳定。所研究的配合物的cd光谱被记录下来,分解成组分带并分配。

Stability and C.D. spectra of Co2+ and Cu2+ complexes with epimeric threonines and isoleucines

Acid dissociation constants of epimeric threonines (Thr, allo-Thr) and isoleucines (Ile, allo-Ile) and the stability constants of their complexes with Co2+ and Cu2+ were determined by potentiometry. The natural epimers form more stable complexes than the allo forms. C.d. spectra of the complexes investigated were recorded, resolved into component bands and assigned.
