Glucose
![](https://commons.wikimedia.org/wiki/Special:FilePath/Alpha-D-glucopyranose-2D-skeletal.png?width=300)
Glucose is a sugar with the molecular formula C6H12O6. The name ""glucose"" (/ˈɡluːkoʊs/) comes from the Greek word γλευκος, meaning ""sweet wine, must"". The suffix ""-ose"" is a chemical classifier, denoting a carbohydrate. It is also known as dextrose or grape sugar. With 6 carbon atoms, it is classed as a hexose, a sub-category of monosaccharides. α-D-glucose is one of the 16 aldose stereoisomers. The D-isomer (D-glucose) occurs widely in nature, but the L-isomer (L-glucose) does not. Glucose is made during photosynthesis from water and carbon dioxide, using energy from sunlight. The reverse of the photosynthesis reaction, which releases this energy, is a very important source of power for cellular respiration. Glucose is stored as a polymer, in plants as starch and in animals as glycogen.
