Properties of synthetic and native liver glycogen
The properties of high molecular weight glycogen extracted from rat liver and of that prepared in vitro with muscle phosphorylase and liver branching enzyme have been compared. The stability at different pH values was measured spectrophotometrically for liver, corn, and synthetic glycogen. The forme...
