Carbon—14- and Tritium-Labeled DPN and TPN
In this article, new methods will be described for the introduction of carbon and hydrogen isotopes into the nicotinamide moiety of the pyridine nucleotides. Compared to the methods already in use, these new methods have the advantages of somewhat greater yields of label incorporated into the pyridine nucleotides and the potential of producing pyridine nucleotides with greater specific activities. As such, they should serve as useful additions to the methods presently available.
