Biosynthesis of glycogen from uridine diphosphate glucose
An enzyme which leads to the formation of glycogen according to the equation: UDPG + primer → UDP + glucosyl α (1 → 4) primer has been studied. The optimal conditions for activity were determined with a partially purified preparation from rat muscle. The reaction requires the presence of a polysacch...
