What is the difference between glucose and glycogen?

Glucose is a monosaccharide, meaning that it is composed of single units. This is suitable for transport through the blood stream. Glycogen, however is a polysaccharide meaning that is composed of at least more than two units. Its purpose is storage of energy (mainly in the liver) which is suited by its tightly packed, linked structure.
