AI overview
Glycogen is a stored form of glucose in your body, made up of thousands of glucose units branched together around a core protein called glycogenin. Your cells break down glycogen when they need quick energy, making it an important fuel reserve for muscles and other tissues.

thumb|right|Glycogen (black granules) in spermatozoa of a [[flatworm; transmission electron microscopy, scale: 0.3 μm]] Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. It is the main storage form of glucose in the human body.
