摘要: On the basis of finding two sets coupling constants (8.8 Hz and 6.7 Hz) in 270-MHz proton magnetic resonance spectra linear Gramicidin dimethylsulfoxide comparison its infrared spectrum with those known conformations alternating poly(γ-benzyl-D-glutamate–γ-benzyl-L-glutamate), it is proposed that antibotic has an LD-ribbon structure.
