Serotonin and tyramine affected dissimilarly the enzyme activity involved in degradation of glycogen in isolated rat hepatocytes. Serotonin inhibited hydrolytic enzymes acid alpha-glucosidase, alpha-amylase and amylo-1,6-glucosidase but activated phosphorylase inducing a decrease of glycogen content in cells. Tyramine inhibited acid alpha-glucosidase and amylo-1,6-glucosidase, did not affect the alpha-amylase and phosphorylase activities and increased content of glycogen in cells. Tyramine may be used as stimulator of glycogen accumulation in liver cells.
