A glucose solution is a liquid mixture that contains glucose, a simple sugar that serves as a primary energy source for the body. It is commonly used in medical settings to provide hydration and energy to patients, especially those who are unable to eat or drink normally. The solution can vary in concentration, typically ranging from 5% to 50% glucose. In addition to medical uses, glucose solutions are also utilized in laboratory settings for various experiments and tests. They can be administered intravenously or taken orally, depending on the specific needs of the patient or the requirements of the experiment.
