The mode of incorporation into nicotinamide of label from13C-labeled samples of D-glucose, in Escherichia coli and Saccharomyces cerevisiae, was determined by means of13C NMR spectroscopy. The results, which confirm and extend early studies with radioactive tracers, permit a definitive choice to be made between alternative biogenetic proposals.Key words: nicotinic acid, nicotinamide, biosynthesis, glucose incorporation,13C NMR.
