Nameglycogen system
TypeSYSTEM
DescriptionGlycogen and starch are related glucose storage polysaccharides. Alpha 1,4 glucan linkages predominate, with some branching using alpha 1,6 linkages. The relative level of branching determines whether the substance is called glycogen or starch. In bacteria and plants, the precursor is ADP-glucose. In animals, the precursor is UDP-glucose. Different forms of glycogen synthase are used for the two. This property is developed here as a system and includes the enzyme phosphorylase (glycogen phosphorylase or starch phosphorylase, depending on context) necessary to release glucose-1-phosphate from the polysaccharide. It is not yet defined here whether glycogen-like storage polymer systems, such as found in Streptococcus mutans, will be included within this property or not.
