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.

Spatial Variability of Nitrogen‐15 Natural Abundance

Soil Science Society of America Journal, 1991
Abstract The primary objective of this study was to investigate the spatial variability of 15 N natural abundance (δ 15 N) in a non‐N 2 ‐fixing plant ( Triticum aestivum

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 ...
