E. Kleinpeter et al., SOLUTION CONFORMATION OF TRIPEPTIDES BY NMR-SPECTROSCOPY AND FORCE-FIELD CALCULATIONS, Structural chemistry, 6(6), 1995, pp. 377-382
The solution conformation of three linear tripeptides Boc-Ala-Val-Val-
OMe 1, Boc-Ala-Pro-Val-OMe 2, and Boc-Ala-(D)Pro-Val-OMe 3 was studied
by NMR spectroscopy and accompanying force-field calculations. In one
case, 2, as preferred conformation the epsilon-turn all trans conform
er was found.
