|"Glycogen molecules are very large they are thus effectively trapped in the cells in which they were made without creating much of an osmotic effect. In view of the hydrophilic nature of carbohydrates, glycogen is associated with ˜3 g water/g glycogen. The energy density of glycogen stores is thus only ˜4.2 kJ/g (˜1 kcal/g), imposing definite limits on the amount of energy that can conveniently be carried in the form of glycogen."
