使用
glycogen is a skin-conditioning agent. It is a high molecular-weight polymer distributed through the cell protoplasm.
定義
A
polysaccharide that is the main carbohydrate
store of animals. It is composed of
many glucose units linked in a similar way
to starch. Glycogen is readily hydrolyzed in
a stepwise manner to glucose itself. It is
stored largely in the liver and in muscle but
is found widely distributed in the body.
一般的な説明
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.
純化方法
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.
