Suppressing one-bond homonuclear 13C,13C scalar couplings in the J-HMBC NMR experiment: application to 13C site-specifically labeled oligosaccharides.
Site-specific (13)C isotope labeling is a useful approach that allows for the measurement of homonuclear (13)C,(13)C coupling constants. For three site-specifically labeled oligosaccharides, it is demonstrated that using the J-HMBC experiment for measuring heteronuclear long-range coupling constants is problematical for the carbons adjacent to the spin label. By incorporating either a selective...
متن کاملVisualizing Unresolved Scalar Couplings by Real-Time J-Upscaled NMR
Scalar coupling patterns contain a wealth of structural information. The determination, especially of small scalar coupling constants, is often prevented by merging the splittings with the signal line width. Here we show that real-time J-upscaling enables the visualization of unresolved coupling constants in the acquisition dimension of one-dimensional (1D) or multidimensional NMR spectra. This...
متن کاملConformational studies of human milk oligosaccharides using (1)H-(13)C one-bond NMR residual dipolar couplings.
1H-(13)C one-bond dipolar coupling values were measured for natural abundance samples of the human milk oligosaccharides "lacto-N-fucopentaose" (LNF-1 LNF-2, and LNF-3), "lacto-N-difucohexaose" (LND-1), "lacto-N-tetraose" (LNT), and "lacto-N-neo-tetraose" (LNnT), four of which have Lewis blood group epitopes. Each oligosaccharide was dissolved in a 7.5% solution of 1, 2-dimyristoyl-sn-glycero-3...
متن کاملA robust, sensitive, and versatile HMBC experiment for rapid structure elucidation by NMR: IMPACT-HMBC.
A robust, versatile and easy to optimize HMBC experiment for complex organic structure elucidation which has been experimentally tested on cholesteryl acetate, cyclosporine and isopropylidene glycerol is described. The proposed experiment, IMPACT-HMBC (improved and accelerated constant-time heteronuclear multiple-bond correlation), combines sensitivity, easy experimental setup and can be record...
متن کاملAn Introduction to Hydrogen Bond Scalar Couplings
( ) ABSTRACT: The hydrogen bond H-bond has been recognized in science for more than 80 years as a concept to explain situations where a hydrogen atom is simultaneously binding to two other atoms. Due to the moderate energies necessary for their formation and rupture, hydrogen bonds play a fundamental role in many chemical reactions and most, if not all, interactions involving biological macromo...
