Metabolism of the Aromatic Amino Acids 175 occur together it is conceivable that the quinones are the biogenetic precursors of the pulvinic acid compounds. Indeed such conversions can be carried out oxidatively in the laboratory and tracer experiments in Pseudocyphellaria crocata have indicated that poly-poric acid (127) can act as a precursor of pulvinic lactone (132). ... [Pg.175]
