Glucose and fructose are formed in equal amounts when sucrose is hydrolyzed by the enzyme invertase or by heating with dilute acid; the resulting equimolar mixture of fructose and glucose, called invert sugar, is the major component of honey.

Fructose

A sugar that is the commonest of ketoses and the sweetest of the sugars. It is also known as d -fructose, d -fructopyranose, and levulose fruit sugar. It is found in free state, usually accompanied by d -glucose and sucrose in fruit juices, honey, and nectar of plant glands. d -Fructose is the principal sugar in seminal fluid. See Carbohydrate

Fructose is readily utilized by diabetic animals. In persons with diabetes mellitus or parenchymal hepatic disease, the impairment of fructose tolerance is relatively small and not at all comparable to the diminution in their tolerance to glucose. See Monosaccharide

Fructose

(fruit sugar, levulose, (β-D-fructose), a colorless crystalline substance, with a sweet taste (1.5 times sweeter than saccharose and three times sweeter than glucose) and a melting point of 102°–104°C.

Fructose is soluble in water. A monosaccharide, it occurs naturally in many fruits and vegetables, such as apples and tomatoes, and in honey (approximately 50 percent) and is a constituent of oligosaccharides and polysaccharides. The phosphates of fructose, such as fructose-l,6-diphosphate and fructose-6-phosphate, are intermediate compounds in the dark phase of photosynthesis (Calvin cycle), in major metabolic processes (glycolysis, alcoholic fermentation), and in the biosynthesis of carbohydrates.

Fructose is a valuable food product and is easily assimilated by the organism. It is obtained from fruits by the hydrolysis of saccharose and inulin, as well as by the action of alkalies on D-glucose. In addition to the furanose (natural) form, the open ketone form and other tautomeric forms of fructose are known. Fructose is used in the food-processing industry and in medicine. Fructose-1,6-diphosphate is a drug administered to persons suffering from shock or various heart conditions.

fructose

[fruk´tōs] a monosaccharide found in honey and many sweet fruits; it is used in solution as a fluid and nutrient replenisher. Called also levulose and fruit sugar.

fruc·tose (Fru),

(fruk'tōs), A sugar that occurs naturally in fruits and honey. The dmonosaccharide is a 2-ketohexose that is the most important of the ketohexoses physiologically and one of the two products of sucrose hydrolysis; it is metabolized or converted to glycogen in the absence of insulin. Also referred to as fruit sugar, levoglucose, levulose, and d-arabino-2-hexulose. [L. fructus, fruit, + -ose]

fructose

A molecule that is half sucrose and half glucose, which has been promoted as a sugar substitute.

Pros
It is 70% sweeter per calorie than other sugars and does not promote caries (tooth decay).

Cons
It is more expensive, loses sweetness with heating and may increase serum lipids in some individuals.

fruc·tose

(fruk'tōs) A ketohexase; the d-isomer (also called fruit sugar, levulose, and d-arabino-2-hexulose) found in fruits and honey; a product of sucrose hydrolysis. It can be metabolized or converted to glucose. [L. fructus, fruit, + -ose]

fructose

One of the simplest forms of sugar (a monosaccharide) and derived from fruit, sugar cane, honey and sugar beet. Fructose, linked to another monosaccharide, glucose, form the disaccharide sucrose which is the common domestic sugar. Fructose is sweeter than glucose, but has the same energy value. It is readily absorbed. Fructose provides direct energy for spermatozoa and is found in seminal fluid.

fructose

a carbohydrate that is considered to be an atypical KETOSE sugar because it acts as a reducing sugar in FEHLING'S TEST. See MONOSACCHARIDE and Fig. 224 .

Patient discussion about fructose

Q. what is more healthy, brown sugar or fruit sugar? A. fruit sugar

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.
