The beginning:
The Isolation and Hydrolysis of Glycogen
Introduction and methods
Glycogen is a polysaccharide. It is composed of long glucose chains with an (14) linked backbone, starting from a
glycoprotein
as an initiating molecule. A chain branching usually occurs after every 8 to 10 glucose residues via (16) linkage. As a result of this structure, glycogen molecule has a globular shape. Glycogen principally serves as a long- term, easily accessible energy storage in animal cells. When energy is needed, glucose units are removed from the glycogen as glucose 1-P. Particularly high concentrations of this polysaccharide can be found in muscle and liver tissues. A diet rich in
sachharide
is required to maintain sufficient levels of polysaccharides,...
