Glucose is a sugar with the molecular formula C 6 H 12 O 6.It is overall the most abundant monosaccharide, [4] a subcategory of carbohydrates.It is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight.
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.

The aqueous solution in the classical reaction contains glucose, sodium hydroxide and methylene blue. [14] In the first step an acyloin of glucose is formed. The next step is a redox reaction of the acyloin with methylene blue in which the glucose is oxidized to diketone in alkaline solution [6] and methylene blue is reduced to colorless leucomethylene blue.
Scientists and the sugar industry use degrees Brix (symbol °Bx), introduced by Adolf Brix, as units of measurement of the mass ratio of dissolved substance to water in a liquid. A 25 °Bx sucrose solution has 25 grams of sucrose per 100 grams of liquid; or, to put it another way, 25 grams of sucrose sugar and 75 grams of water exist in the 100 ...
[6] [7] [8] According to the American Diabetes Association, the fasting blood glucose target range for diabetics, should be 3.9 - 7.2 mmol/L (70 - 130 mg/dL) and less than 10 mmol/L (180 mg/dL) two hours after meals (as measured by a blood glucose monitor). [6] [7] [9] Normal value ranges may vary slightly between laboratories.

Glycan nomenclature is the systematic naming of glycans, which are carbohydrate-based polymers made by all living organisms. In general glycans can be represented in (i) text formats, these include commonly used CarbBank, IUPAC name, and several other types; and (ii) symbol formats, these are consisting of Symbol Nomenclature For Glycans and Oxford Notations.
