Glucose : Glucose: The simple sugar (monosaccharide) that serves as the chief source of energy in the body. Glucose is the principal sugar the body makes. The body makes glucose from proteins, fats
and, in largest part, carbohydrates. Glucose is carried to each cell through the bloodstream. Cells, however, cannot use glucose without the help of { insulin . Glucose is also known as dextrose.
Glucose may be consumed or given IV to increase the level of blood glucose when the level falls too low ( hypoglycemia ). In hypoglycemia, cells cannot function normally, and symptoms develop such
as nervousness, cool skin, headache, confusion, convulsions or coma. Ingested glucose is absorbed directly into the blood from the intestine and results in a rapid increase in the blood glucose. IV
glucose acts even more rapidly to relieve hypoglycemia.
