Glucose-containing compounds are digested and taken up by the body in the intestines, including starch, glycogen, disaccharides and as monosaccharide. Glucose is stored in mainly the liver and muscles as glycogen. It is distributed and utilized in tissues as free glucose. To discuss image, please see Template talk:Human body diagrams
B-type chains, making half of the branches, have two branch points, and all chains have the same length. E. Meléndez-Hevia, R. Meléndez and E. I.

The glycogen in the liver can function as a backup source of glucose between meals. [2] Liver glycogen mainly serves the central nervous system. Adrenaline stimulates the breakdown of glycogen in the skeletal muscle during exercise. [12] In the muscles, glycogen ensures a rapidly accessible energy source for movement. [2]
Glycogen is analogous to starch, a glucose polymer in plants, and is sometimes referred to as animal starch, [16] having a similar structure to amylopectin but more extensively branched and compact than starch. Glycogen is a polymer of α(1→4) glycosidic bonds linked with α(1→6)-linked branches.
Liver glycogen stores serve as a store of glucose for use throughout the body, particularly the central nervous system. [4] The human brain consumes approximately 60% of blood glucose in fasted, sedentary individuals. [4] Glycogen is an analogue of starch, a glucose polymer that functions as energy storage in plants.
polysaccharide: cellulose – carbohydrate – chitin – glycogen – starch proteins : primary structure – secondary structure – tertiary structure – conformation – native state – protein folding – enzyme – receptor – transmembrane receptor – ion channel – membrane transporter – collagen – pigments : chlorophyll ...
Starch phosphorylase is a form of phosphorylase similar to glycogen phosphorylase, except that it acts upon starch instead of glycogen.. The plant alpha-glucan phosphorylase, commonly called starch phosphorylase (EC 2.4.1.1), is largely known for the phosphorolytic degradation of starch.
Two common examples are cellulose, a main component of the cell wall in plants, and starch, a name derived from the Anglo-Saxon stercan, meaning to stiffen. [ 2 ] To name a polysaccharide composed of a single type of monosaccharide, that is a homopolysaccharide, the ending “-ose” of the monosaccharide is replaced with “-an”. [ 3 ]
