Dietary Adaptation and the Level of Glucose-6-Phosphatase and Phosphohexoseisomerase of Rat Liver

Abstract

Dietary adaptation to high-fat and high-carbohydrate diets was shown to modify the absorptive and post-absorptive levels of liver glucose-6-phosphatase activity in the rat. Fasting levels were higher in the animals previously fed carbohydrate diets. Fat adaptation, however, decreased the activity of liver phosphohexoseisomerase during absorption and fasting.
