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
Oyster glycogen has been used to induce inflammation and to promote extravasation of granulocytes and neutrophils in animal models after intraperitoneal injection. Glycogen also acts as a vascular permeability probe.
Other Notes
High molecular weight

Animals can determine the nutritional value of sugar without the influence of taste. We examined a Drosophila mutant that is insensitive to the nutritional value of sugars, responding only to the concentration (that is, sweetness). The affected gene encodes a
Parasitic castration in the snail-trematode relationship can be understood as any change in the reproductive function of the snail that is due to interference by the developing larvae inside the snail that leads to the reduction or complete disruption of
In a previous study we reported impaired swimming performance and greater stored energy in adult zebrafish (Danio rerio) after chronic dietary exposure to selenomethionine (SeMet). The goal of the present study was to further investigate effects of chronic exposure to

Glucose is stored in skeletal muscle fibers as glycogen, a branched-chain polymer observed in electron microscopy images as roughly spherical particles (known as β-particles of 10-45 nm in diameter), which are distributed in distinct localizations within the myofibers and are
The physiological relevance of acid maltase (acid α-glucosidase, an enzyme that degrades lysosomal glycogen) is well recognized in liver and muscle. In late (adult)-onset acid maltase deficiency (glycogen storage disease type II [GSD II]), glycogen accumulates inside muscular lysosomes in
