<P> Approximately 4 grams of glucose are present in the blood of humans at all times ; in fasted individuals , blood glucose is maintained constant at this level at the expense of glycogen stores in the liver and skeletal muscle . Glycogen stores in skeletal muscle serve as a form of energy storage for the muscle itself ; however , the breakdown of muscle glycogen impedes muscle glucose uptake , thereby increasing the amount of blood glucose available for use in other tissues . Liver glycogen stores serve as a store of glucose for use throughout the body , particularly the central nervous system . The human brain consumes approximately 60 % of blood glucose in fasted , sedentary individuals . </P>
