glucose

A Dictionary of Nursing | 2008 | Â© A Dictionary of Nursing 2008, originally published by Oxford University Press 2008. (Hide copyright information) Copyright

glucose (dextrose) (gloo-kohz) n. a simple sugar containing six carbon atoms (a hexose). Glucose, an important source of energy, is one of the constituents of both sucrose and starch, both of which yield glucose after digestion. It is stored in the body in the form of glycogen. If the blood-glucose concentration falls below the normal level of around 5 mmol/l, neurological and other symptoms may result (see hypoglycaemia). If the blood-glucose level is raised to 10 mmol/l, the condition of hyperglycaemia develops. This is a symptom of diabetes mellitus.
