15 صفحه اولInteractions of the carboxyl group of oleic acid with bovine serum albumin: a 13C NMR study.
The interactions of the carboxyl group of oleic acid with bovine serum albumin (BSA) were studied by 13C NMR spectroscopy at 50.3 MHz using 90% isotopically substituted [1-13C]oleic acid. 13C NMR spectra were obtained as a function of the mole ratio of oleic acid to BSA (from 0.5-10.0) and, for selected mole ratios, as a function of pH (between pH 3.0 and 10.6) and temperature (between 15 and 5...
متن کاملParameterization of peptide 13C carbonyl chemical shielding anisotropy in molecular dynamics simulations.
NMR chemical shielding anisotropy (CSA) relaxation is an important tool in the study of dynamical processes in proteins and nucleic acids in solution. Herein, we investigate how dynamical variations in local geometry affect the chemical shielding anisotropy relaxation of the carbonyl carbon nucleus, using the following protocol: 1) Using density functional theory, the carbonyl (13)C' CSA is com...
متن کامل13C chemical shielding in oxalic acid, oxalic acid dihydrate, and diammonium oxalate
13C chemical shielding tensors in three oxalates were investigated in order to determine the effe~ts of protonation and conformation changes on the tensor elements and their orientations. The expenmental results. together with those in the accompanying paper [R. G. Griffin and D. J. Ruben, J. Chern. ~hys. 63, 1272 (1975)], indicate that, while neither of these factors seems to seriously effect ...
متن کاملProton magnetic shielding tensor in liquid water.
The nuclear magnetic shielding tensor is a sensitive probe of the local electronic environment, providing information about molecular structure and intermolecular interactions. The magnetic shielding tensor of the water proton has been determined in hexagonal ice, but in liquid water, where the tensor is isotropically averaged by rapid molecular tumbling, only the trace of the tensor has been m...
