In vivo determination of the pyridine nucleotide reduction charge by carbon-13 nuclear magnetic resonance spectroscopy.
TLDR
An intracellular coenzyme has been observed by carbon-13 nuclear magnetic resonance spectroscopy by monitoring the redox status and metabolic transformations of the pyridine nucleotides in Escherichia coli under a variety of conditions. Expand
Structural Biochemistry 14. Permethylation of Nucleosides
Abstract Prominent molecular ions are generally observed in the field ionization (FI) mass spectra of unprotected nucleosides.2 In the one exception so far observed, that of guanosine, we found theExpand
A CARBON‐13 NUCLEAR MAGNETIC RESONANCE SPECTROSCOPIC INVESTIGATION OF THE KILIANI REACTION
The Kiliani reaction of D-arabinose with sodium (/sup 13/C)cyanide (or (/sup 13/C,/sup 15/N)cyanide) was studied by /sup 13/C NMR. The C-1 resonances of intermediates and products were observed asExpand
Antineoplastic agents. 51. The yellow jacket Vespula pensylvanica.
An ethyl alcohol extract of the yellow jacket Vespula pensylvanica Saussure was found to inhibit growth of the murine P388 lymphocytic leukemia cell line. Separation of a ligroin fraction guided byExpand
