What Fraction of the Body's Total Glycogen Content Is Found in the Liver?

Although it is true that hepatic tissues of the liver store the highest amount of glucose as glycogen relative to muscle tissues, the liver actually only holds 40 percent of the body's glycogen. This is simply because there is significantly more muscle tissue, notes Orthomolecular.org.

Most introductory biology and health classes teach that the liver stores the most glycogen in the human body, which is only slightly incorrect. The liver stores glycogen at the highest rate of all body tissues, but since the liver makes up less than 10 percent of the total tissue in the human body, as compared to the 50 percent or more of total tissue made up by muscle, the liver actually stores less glycogen mass than muscle, according to Orthomolecular.org.
