Hexose metabolism in pancreatic islets: glycogen synthase and glycogen phosphorylase activities.

The activity of glycogen synthase and glycogen phosphorylase was measured in rat pancreatic islet homogenates. For this purpose, the sensitivity of current radioisotopic procedures for the assay of these enzymes in liver extracts was increased by about two orders of magnitude. Even so, the measurement of glycogen synthase and phosphorylase in islet… CONTINUE READING
