What monosaccharides make up glycogen?
Only one monosaccharide makes up glycogen, and that is glucose.
The structure of glucose,
Glycogen is a chain of glucose subunits held together by 1→4-glycoside bonds, but it is a highly branched structure.
Every 8 to 10 glucose units, branches are joined by 1→6-glycoside bonds.
We could write the equation for the formation of glycogen as
