glucose

(glo͞o′kōs′)
n.
1. A monosaccharide sugar, C6H12O6, that is used by living things to obtain energy through the process of aerobic respiration within cells. It is the principal circulating sugar in the blood of humans and other mammals.
2. A colorless to yellowish syrupy mixture of dextrose, maltose, and dextrins containing about 20 percent water, used in confectionery, alcoholic fermentation, tanning, and treating tobacco. Also called starch syrup.

glucose

Biochemistry The hexose sugar that is the main source of energy in mammals. See Random glucose.

glu·cose

(glū'kōs)
A dextrorotatory monosaccharide found in a free form in fruits and other parts of plants, and in combination in glucosides, glycogen, disaccharides, and polysaccharides (starch cellulose); the chief source of energy in human metabolism, the final product of carbohydrate digestion, and the principal sugar of the blood; insulin is required for the use of glucose by cells; in diabetes mellitus, the level of glucose in the blood is excessive, and it also appears in the urine.
Synonym(s): d-glucose.

glucose

Grape or corn sugar. Glucose is a simple monosaccharide sugar present in the blood as the basic fuel of the body. Glucose is essential for life; a severe drop in the blood levels rapidly leads to coma and death. It is stored in the liver and the muscles in a polymerized form called GLYCOGEN. It is derived from carbohydrates in the diet, but in conditions of shortage can be synthesized from fats or proteins. The sugar is on the WHO official drug list.

glucose

or

dextrose

an important hexose sugar with an ALDOSE structure that occurs in two forms, alpha and beta; it has the general formula C6 H12 O6 and is found in sweet fruits, especially ripe grapes. Glucose is formed in the CALVIN CYCLE of PHOTOSYNTHESIS and acts as a primary energy supply for both plant and animal cells, although usually it is converted to an insoluble form for long-term storage: STARCH in plants, GLYCOGEN in animals. see MONOSACCHARIDE for structure.

Glucose

A simple sugar produced when carbohydrates are broken down in the small intestine. It is the primary source of energy for the body. Various tests that measure blood glucose levels are used in diagnosing insulin resistance.

Patient discussion about Glucose

Q. What difference does fructose makes to a diabetic with respect to glucose? I am diabetic with type 2 NIDDM. My colleague with the same NIDDM type2 has a better glycemic control than me. He follows strict diet. He prefers fructose sugar and avoids other sugar as much as possible. He suggested me the same. What difference does fructose makes to a diabetic with respect to glucose?

A. All carbohydrates—like starch and sugars like dextrose, maltose and glucose must be controlled for high consumption by a diabetic. Whereas fructose sugar had a slight different metabolic route inside the body and it does not requires insulin. Glucose requires insulin. As a diabetic lacks insulin production; the glucose increases the sugar level of the body but fructose is out of this system of functioning by our body and makes a diabetic to control it well. The energy level of glucose and fructose are almost similar.

Q. When will I have the Glucose Tolerance Test? I am pregnant and wanted to know when I need to have the Glucose Tolerance Test and what is the test like.

A. The test is given between week 24 and week 28 of the pregnancy. First you drink glucose, which is very sweet. You can mix it will water to help it go down easier. Then, after an hour you will have a blood test to check your glucose levels.

Q. What Do my Oral Glucose Tolerance Test Results Mean? I had an Oral Glucose Tolerance Test last week. I am 26 weeks pregnant. The results I got are 132 mg/dL. What does this mean?

A. If your blood glucose level was greater than 130 mg/dL, your provider will likely recommend you take another diabetes screening test that requires you to fast (not eat anything) before the test. During this second test, called the 100-gram oral glucose tolerance test, your blood glucose level will be tested four times during a three-hour period after drinking the cola-like drink. If two out of the four blood tests are abnormal, you are considered to have gestational diabetes.
