Studies on Turnover Rate of Cardiac Glycogen In Vivo and In Vitro by Single Injection of C14-glucose

Abstract

Glycogen is the most important storage form of carbohydrate in the heart as in other tissues. Therefore, the participation of this substance in metabolic processes, the mode of its synthesis and the mechanism of its degradation are of importance to the understanding of biochemistry of carbohy drate fuels and their utilization by animal tissues. Over the recent years, a number of studies have provided data on metabolic and kinetic problems of glycogen turnover employing isotopic tracer techniques.
