Factors Influencing Glycogen Branching Enzyme Activity In Mouse Liver, Scott Fuller

LSU Doctoral Dissertations

Glycogen is the storage polysaccharide in a spectrum of organisms ranging from yeast to humans. Glycogen has a highly branched structure somewhat resembling a tree or shrub, with the branch points formed by glucose molecules being joined by α 1,6-glycosidic linkages. These linkages are formed by the action of branching enzyme. Branching of glycogen is critical to health, with a lack of branching causing glycogen storage disease type IV, which is fatal in humans by age 2. While glycogen branching enzyme has been studied in clinical medicine, modulation of the enzyme has received comparatively little attention. This dissertation undertook three …
