Agricultural biochemistry: reaction mechanisms and pathways in biosynthesis

Plant tracer studies in research concerning human food chains are reviewed in the following sections: tracer studies with 14C (photosynthesis and other biosynthesis pathways in plants, intermediary carbon pathways), tracer studies with 13C (13C NMR spectrometry and its applications in biosynthesis pathways), the fate of hydrogen, deuterium as a tracer, triton magnetic resonance spectrometry, double label isotope ratios (reaction mechanism studies and studies of precursor-product relationships), kinetic isotope effects, 18O and organic mass spectrometry, 18O and 31P NMR, precursor-product incorporation and dilution.
