Description and Uses

D(+)-Glucose is one of the most important biological compounds found in nature. It is a main product in photosynthesis and is oxidized in cellular respiration. D(+)-Glucose polymerizes to form several important classes of biomolecules including cellulose, starch, and glycogen. It also combines with other compounds to produce common sugars such as sucrose and lactose. The form of D(+)-Glucose displayed above is D-D(+)-Glucose. The “D” designation indicates the configuration of the molecule. The “D” configuration specifies that the hydroxyl group on the number 5 carbon is on the right side of the molecule. The mirror image of D-D(+)-Glucose produces another form of D(+)-Glucose called L-D(+)-Glucose.D(+)-Glucose is the most common form of a large class of molecules called carbohydrates. Carbohydrates are the predominant type of organic compounds found in organisms and include sugar, starches, and fats. Carbohydrates, as the name implies, derive their name from D(+)-Glucose,C6H12O6, which was considered a hydrate of carbon with the general formula of Cn(H2O)n, where n is a positive integer. Although the idea of water bonded to carbon to form a hydrate of carbon was wrong, the term carbohydrate persisted. Carbohydrates consist of carbon, hydrogen, and oxygen atoms, with the carbon atoms generally forming long unbranched chains. Carbohydrates are also known as saccharides derived from the Latin word for sugar, saccharon.

Glucose is a corn sweetener that is commercially made from starch by the action of heat and acids or enzymes, resulting in the complete hydrolysis of the cornstarch. There are two types of refined commercially available: hydrate, which contains 9% by weight water of crystallization and is the most often used, and anhydrous glucose, which contains less than 0.5% water. is a reducing sugar and produces a high-temperature browning effect in baked goods. It is used in ice cream, bakery products, and confections. It is also termed corn sugar.
