The glycolytic effect of 1-epinephrine and nor-epinephrine on the liver of the chick embryo.

The glycolytic effect of 1-epinephrine and nor-epinephrine administered in-ovo for two hours on the liver of the chick embryo is reported. 1-epinephrine was more glycolytic than nor-epinephrine throughout the study. The glycolytic effect of 1-epinephrine was dosage-dependent throughout the study while nor-epinephrine brought about dosage-dependent liver-glycogen-depletion only in the nine day embryo.
