Nitrogen-15 NMR in Biological Systems

1983
Nitrogen is found in almost every biological system. Active centers of enzymes contain nitrogen in the charged amino acid side chains; in coenzymes and nucleic acids nitrogen forms the essential functional part of the molecule. In particular histidine, arginine, and lysine are important in many enzymes.

Application of nitrogen-15 NMR to polymers

Advances in polymer science, 1995
A large number of polymers for commercial use as well as biological macromolecules are based on nitrogen containing monomers. Thus, the understanding of their structure and molecular dynamics is of great importance. Practical observation of low natural abundance and sensitivity of N-15 isotope was made possible with the development of Fourier Transform

Application of nitrogen-15 NMR to polymers

2005
A large number of polymers for commercial use as well as biological macromolecules are based on nitrogen containing monomers. Thus, the understanding of their structure and molecular dynamics is of great importance. Practical observation of low natural abundance and sensitivity of 15N isotope was made possible with the development of Fourier Transform ...

Automatic nitrogen-15 analyser for use in biological research

The Analyst, 1986
An automatic nitrogen-15 analyser capable of analysing 12–20 samples per hour has been developed. The generation of pure nitrogen gas from the sample is carried out automatically, the nitrogen isotope ratio is determined by emission spectrometry and the results are calculated as atom-% nitrogen-15.
