The ‘D’ in D(+)-glucose represents its configuration, specifically indicating its relation to the D isomer of glyceraldehyde. It is not directly related to the optical activity of the compound, which is denoted by the ‘(+)’ symbol representing its dextrorotatory nature.

Glucose’s reaction with hydroxylamine to form an oxime, addition of hydrogen cyanide to give cyanohydrin, and oxidation to form gluconic acid with bromine water all confirm the presence of a carbonyl group (>C = O) as an aldehydic group in ...

The structure of glucose was determined based on evidence such as its molecular formula (C₆H₁₂O₆), formation of n-hexane upon prolonged heating with HI, reactions with hydroxylamine and hydrogen cyanide confirming the carbonyl group, oxidation to gluconic acid, and acetylation yielding ...

Glucose, also known as dextrose, serves as the monomer for larger carbohydrates such as starch and cellulose.

Commercial glucose is obtained by hydrolyzing starch through boiling it with dilute H₂SO₄ at 393 K under pressure. Starch serves as the raw material for this process.
