Existing methods for the estimation of relative participation of
glucose catabolic pathways make use of yield data of respiratory
¹⁴CO₂ or intermediary ¹⁴C products derived from glucose substrates
specifically labeled with ¹⁴C. Cumulative yields of respiratory
¹⁴CO₂ observed at the end of time course of complete substrate
utilization are analyzed...
An attempt has been made to elucidate the biosynthetic precursor
of ethylene in the mold P. digitatum. By application of basic
radiotracer methodology and the utilization of several specifically
labeled radiochemical substrates, it has been possible to demonstrate
that the internal carbon atoms of C-4 dicarboxylic acids such
as succinate,...
