Water proton transverse relaxation times (T 2 ) and self-diffusion coefficients (D) were measured in randomly oriented hydrated collagen fibers. Three T 2 relaxation times were discerned indicating the presence of at least three water fractions in the collagen sample. The D values associated with ea

The conformation of angiotensinogen, a tetradecapeptide, with the sequence Asp1ΓArg2ΓVal3ΓTyr4Γ Ile5ΓHis6ΓPro7ΓPhe8ΓHis9ΓLeu10ΓLeu11ΓVal12ΓTyr13ΓSer14, was studied in aqueous medium by 2D NMR spectroscopy. Complete resonance assignments were made using a combination of DQF-COSY, TOCSY and NOESY spec
Ψ1 , respectively. The results for the residual dipolar interactions were verified by repeating the above measurements at a temperature of 1.5Β°C, where the spectra of the H 2 O molecules were well resolved, so that the 1 H-1 H dipolar interaction could be determined directly from the observed splitt
