In vitro synthesis of particulate glycogen from uridine diphosphate glucose. II. Some studies on the growth process
It was found that for the same extent of synthesis, the glycogen synthesized in vitro by liver glycogen synthetase (uridine diphosphate glucose: α-1,4-glucan α-4-glucosyltransferase, EC 2.4.1.11) from uridine diphosphate glucose is heavier than that synthesized from glucose 1-phosphate by muscle pho...
