General description

Glycogen is a branched polymer of glucose synthesized by animal cells for energy storage and release. It is constructed of predominantly α1→4 glycosidic bonds with branches created through α1→6 glycosidic bonds.

Application

Glycogen from bovine liver may be used in carbohydrate storage and metabolism research and to study various enzymes such as alpha-glucosidase(s) (GAA) and glycogen phosphorylase(s) (GPase). Glycogen may be used as a substrate to identify and characterize its metabolizing enzymes.

Preparation Note

Prepared by a modification of the procedure of Bell, et al., Biochem. J., 28, 882 (1934).

  5. What are glycogens?  

    Per Biochemistry, Lehninger ed., 2nd ed, p. 266: A general description of glycogens is: A polymer of alpha (1->4) linked D-Glucose with alpha (1->6) branching at about ever 8 to 12 glucose residues. The molecular weight for bovine source is not mentioned, but glycogen in general is 270,000-3.5 million.

  6. What is the solubility of Product G0885, Glycogen from Bovine Liver?

    Sigma routinely tests the solubility in water at 50 mg/mL, yielding a hazy solution. In general, glycogens are soluble in water with opalescence and insoluble in alcohol.
