1H NMR Spectroscopy Profiling of Metabolic Reprogramming of Chinese Hamster Ovary Cells upon a Temperature Shift during Culture [PDF]

, 2013
We report an NMR based approach to determine the metabolic reprogramming of Chinese hamster ovary cells upon a temperature shift during culture by investigating the extracellular cell culture media and intracellular metabolome of CHOK1 and CHO-S cells ...

Stochastic models (cooperative and non-cooperative) for NMR analysis of the hetero-association of aromatic molecules in aqueous solution [PDF]

, 2006
Stochastic cooperative (STOCH-C) and non-cooperative (STOCH-NC) models have been developed for NMR analysis of the hetero-association of aromatic compounds in solution, in order to take into account all physically meaningful association reactions of ...

Structural Identification and Complete NMR Spectral Assignments of 4-Isopropoxy-1-(trifluoroacetyl)naphthalene

Chinese Journal of Magnetic Resonance
In this paper, one-dimensional (1H NMR, 13C NMR, DEPT, and 19F NMR) and two-dimensional NMR (1H-1H COSY, 1H-13C HMBC, and 1H-13C HSQC) techniques were applied to perform structural identification and NMR spectral assignments of the fluorine-containing ...

Combined experimental and computational 1H NMR study of water adsorption onto graphenic materials

Journal of Magnetic Resonance Open, 2023
The effects caused by the interaction with graphene-like layers on the 1H NMR spectra of water molecules adsorbed onto porous carbon materials were investigated by a combination of shielding calculations using density functional theory (DFT) and 1H NMR ...

Sequences of Copolyesters by 1H NMR and 31P NMR Spectroscopy [PDF]

Polymer Journal, 1998
31P NMR and 1H NMR spectra of copolyesters containing phosphorus compounds, obtained by ester-exchange reaction, were studied. Poly(ethylene terephthalate) was used as the main component and poly(hydroquinone phenylphosphate), poly[bis(4-hydroxyphenyl)sulfonephenylphosphate], and poly[bis(4-hydroxyphenyl)sulfonemethylphosphate], as phosphorus compounds.

NMR Characterization of Flavanone Naringenin 7-O-Glycoside Diastereomer

Chinese Journal of Magnetic Resonance, 2017
To discriminate R and S flavanone glycoside using NMR, the mixture of R and S naringenin 7-O-glycoside was first isolated from Gleditsia sinensis. 1H and 13C NMR data of the mixture were recorded with 1H NMR, 13C NMR, 1H-1H COSY, 1H-13C HSQC and 1H-13C ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
