Line 1: Line 1:
 +(1) 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 [[protein]]s,​ 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.
 +
 +(2) (Science: biochemistry) D glucose, a monosaccharide (hexose), C6H12O6, found in certain foods, especially fruits and in the normal [[blood]] of all animals. It is the end product of carbohydrate metabolism and is the chief source of energy for living [[organism]]s,​ its utilisation being controlled by insulin. ​
 +
 +excess glucose is converted to glycogen and stored in the liver and muscles for use as needed and, beyond that, is converted to fat and stored as [[adipose]] [[tissue]]. Glucose appears in the urine in [[http://​www.lymphedemapeople.com/​thesite/​lymphedema_and_diabetes.htm|diabetes]] mellitus. ​
 +
 +Synonym: dextrose. ​
 +
 +Origin: gr. Gleukos = sweetness, glykys = sweet a monosaccharide sugar that has several forms; an important source of physiological energy.Glucose is the compound that is used as a means of energy in both animals and plants, obtained by animals via foodstuff and produced in the calvin cycle by plants. Glucose has a chemical formula of C6H12O6 and can occur in two forms, alpha and beta.
