The compounds D-glucose or dextrose is 2,3,4,5,6-pnetahydroxyhexaldehayde, or conventionally expressed as C6H12O6 with a molecular weight of 180,6 kDa. Glucose is readily soluble in water in a powder form.
Glucose is also the primary repeating sugar unit of most complex carbohydrates or starch.
While many foods contain traces of glucose, it is found in significant amounts only in fruits, such as grapes.
Photosynthesis converts carbon dioxide and water to glucose, which is stored in leaves, stems, fruits, roots, pods and seeds, as glucose, as other sugars or as starch.
The small, amount of glucose in the blood and cells provides the energy need for human body’s daily activities. Any galactose or fructose that is absorbed into the blood is converted to glucose by enzymes present in the liver. It is an essential energy source for the adult human brain.
Glucose is stored as glycogen, an α-link polymer, predominantly in the liver and muscles. On average m a 70 kg man may store 500g of glycogen.
