White to off-white powder | [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. | [Biochem/physiol Actions]
Glycogen from rabbit liver helps in maintaining blood glucose levels by regulating the release of glucose in between meals. It also provides energy during sudden, strenuous activity. Two important areas of glycogen storage are the liver and skeletal muscle. | [Purification Methods]
A 5% aqueous solution (charcoal) of D(+)-glycogen is filtered, and an equal volume of EtOH is added. After standing overnight at 3o the precipitate is collected by centrifugation, washed with absolute EtOH, then EtOH/diethyl ether (1:1) and diethyl ether, and dried.
