Incorporation of phosphate into glycogen by glycogen synthase [PDF]
Archives of Biochemistry and Biophysics, 2016 The storage polymer glycogen normally contains small amounts of covalently attached phosphate as phosphomonoesters at C2, C3 and C6 atoms of glucose residues. In the absence of the laforin phosphatase, as in the rare childhood epilepsy Lafora disease, the phosphorylation level is elevated and is associated with abnormal glycogen structure that ...

Glycogen Metabolism in Glycogen-rich Erythrocytes [PDF]
Blood, 1974 Abstract High concentrations of red blood cell glycogen were visualized by electron microscopy and demonstrated biochemically in amylo-1,6-glucosidase- and phosphorylase-deficient red blood cells. Glycogen concentration decreased as a function of cell age.

Glycogen metabolism and glycogen storage disorders [PDF]
Annals of Translational Medicine, 2018 Glucose is the main energy fuel for the human brain. Maintenance of glucose homeostasis is therefore, crucial to meet cellular energy demands in both - normal physiological states and during stress or increased demands. Glucose is stored as glycogen primarily in the liver and skeletal muscle with a small amount stored in the brain.

Action Patterns of Phosphorylase and Glycogen Synthetase on Glycogen [PDF]
European Journal of Biochemistry, 1970 The action patterns of liver and muscle glycogen synthetases and of muscle phosphorylase b on glycogen samples of different molecular weight and on β‐amylase limit dextrins were studied. For this purpose a method for measuring the number of newly added glucose residues that are at non‐reducing ends was developed.It was found that glucose transfer to ...

Frontiers in Physiology, 2023 Important changes in glucose transporter (GLUT) expression should be expected if the glucose influx plays a pivotal role in fuelling or connecting metabolic pathways that are upregulated in response to exercise.

International Journal of Translational Medicine, 2021 Glycogen is present in all tissues, but it is primarily stored in the liver and in muscle. As a branched chain carbohydrate, it is broken down by phosphorylase and debrancher enzymes, which are cytoplasmic.

Role of Astrocytes in the Pathophysiology of Lafora Disease and Other Glycogen Storage Disorders
Cells, 2023 Lafora disease is a rare disorder caused by loss of function mutations in either the EPM2A or NHLRC1 gene. The initial symptoms of this condition are most commonly epileptic seizures, but the disease progresses rapidly with dementia, neuropsychiatric ...

Hepatology Communications, 2019 Mutations in the liver glycogen phosphorylase (Pygl) gene are associated with the diagnosis of glycogen storage disease type VI (GSD‐VI). To understand the pathogenesis of GSD‐VI, we generated a mouse model with Pygl deficiency (Pygl−/−).
