It serves as a key energy source in medicine (IV fluids oral rehydration) food industry (sweetener fermentation substrate for brewing) and biochemistry (cell culture media chromatography standards).

Its primary purpose is to provide rapid energy via glycolysis in biological systems act as a reducing sugar in analytical tests (e.g. Fehlings or Benedicts) and stabilize proteins or enzymes in lab buffers.

D()-Glucose commonly known as dextrose is a naturally occurring simple sugar and aldohexose with the molecular formula C6H12O6 existing primarily as white crystalline - or -anomers that are highly soluble in water and exhibit mutarotation in solution.
