Glucose is readily metabolised into carbon dioxide and water, with a release of energy. As such,
an administration of a glucose solution either by oral or parenteral route provides water for body
hydration as well as calories. In addition, it may reduce catabolic loss of nitrogen from the body
and aids in prevention of depletion of liver glycogen. That is, in the absence of glucose, amino
acids undergo deamination. It is followed by oxidation, with a release of energy. Thus, the
Glucose 5% infusion solutions and the Glucose 10% infusion solutions have value as a source
of water and energy.
Glucose is readily converted into fat in the body which can be used as a source of energy as
required. Under a similar conversion into storage of energy, glucose is stored in the liver and muscles as glycogen. For a quick rise in plasma glucose, glycogen is readily converted into
glucose.
