Abstract

quinone derived from eriodictyol. The compound absorbing at 475 quinone derived from eriodictyol. The compound absorbing at 475 quinone derived from eriodictyol. The compound absorbing at 475 quinone derived from eriodictyol. The compound absorbing at 475 nm must be derived from this eriodictyol-o-quinone. Progress curves at this wavelength revealed a lag, the length nm must be derived from this eriodictyol-o-quinone. Progress curves at this wavelength revealed a lag, the length nm must be derived from this eriodictyol-o-quinone. Progress curves at this wavelength revealed a lag, the length nm must be derived from this eriodictyol-o-quinone. Progress curves at this wavelength revealed a lag, the length nm must be derived from this eriodictyol-o-quinone. Progress curves at this wavelength revealed a lag, the length of which varied with enzyme and substrate concentrations. This lag must have been caused by chemical reacof which varied with enzyme and substrate concentrations. This lag must have been caused by chemical reacof which varied with enzyme and substrate concentrations. This lag must have been caused by chemical reacof which varied with enzyme and substrate concentrations. This lag must have been caused by chemical reacof which varied with enzyme and substrate concentrations. This lag must have been caused by chemical reactions taking place after the enzymatic r tions taking place after the enzymatic r tions taking place after the enzymatic r tions taking place after the enzymatic r tions taking place after the enzymatic reaction.
