title: Application of 15N-nuclear magnetic resonance (N.M.R.) spectroscopy for the study of nitrogen metabolism of a parasite: transamination in Angiostrongylus cantonensis eggs.
abstract: In an attempt to study nitrogen metabolism in a parasite, we applied 15N-nuclear magnetic resonance (NMR) technology with a stable isotope, a 15N-labeled compound, for the study of the transamination system in A. cantonensis eggs, and demonstrated that 15N-aspartic acid can serve as an amino group donor for both the 2-oxoglutaric-glutamic acid and the pyruvic acid-alanine transamination systems in the eggs.
