Reducing form of glucose (the aldehyde group is on the far right) A reducing sugar is any sugar that is capable of acting as a reducing agent. [1] In an alkaline solution, a reducing sugar forms some aldehyde or ketone, which allows it to act as a reducing agent, for example in Benedict's reagent. In such a reaction, the sugar becomes a ...
In all glucose polymers, from the native starch to glucose syrup, the molecular chain ends with a reducing sugar, containing a free aldehyde in its linear form. As the starch is hydrolysed, the molecules become shorter and more reducing sugars are present. Therefore, the dextrose equivalent describes the degree of conversion of starch to dextrose.
Glucose can be obtained by hydrolysis of carbohydrates such as milk sugar , cane sugar (sucrose), maltose, cellulose, glycogen, etc. Dextrose is commonly commercially manufactured from starches, such as corn starch in the US and Japan, from potato and wheat starch in Europe, and from tapioca starch in tropical areas.

Corn syrup – sweet syrup produced from corn starch that may contain glucose, maltose and other sugars. Date sugar [1] Dehydrated cane juice [1] Demerara sugar [1] Dextrin [1] – an incompletely hydrolyzed starch made from a variety of grains or other starchy foods. Dextrose [1] – same as glucose, dextrose is an alternative name of glucose
For many monosaccharides (including glucose), the cyclic forms predominate, in the solid state and in solutions, and therefore the same name commonly is used for the open- and closed-chain isomers. Thus, for example, the term "glucose" may signify glucofuranose, glucopyranose, the open-chain form, or a mixture of the three.
Sugar can be a part of a healthy, balanced diet—after all, our brain's primary source of fuel is glucose (aka sugar). The health issues arise only when you eat more sugar than you need.
l-Glucose is an organic compound with formula C 6 H 12 O 6 or O=CH[CH(OH)] 5 H, specifically one of the aldohexose monosaccharides. As the l-isomer of glucose, it is the enantiomer of the more common d-glucose. l-Glucose does not occur naturally in living organisms, but can be synthesized in the laboratory.
This is also called dextrose, or grape sugar because drying grape juice produces crystals of dextrose that can be sieved from the other components. [75] Glucose syrup is a liquid form of glucose that is widely used in the manufacture of foodstuffs. It can be manufactured from starch by enzymatic hydrolysis. [76]
