glucose
/ glo̅o̅′kōs′ /
- A monosaccharide sugar found in plant and animal tissues. Glucose is a product of photosynthesis, mostly incorporated into the disaccharide sugar sucrose rather than circulating free in the plant. Glucose is essential for energy production in animal cells. It is transported by blood and lymph to all the cells of the body, where it is metabolized to form carbon dioxide and water along with ATP, the main source of chemical energy for cellular processes. Glucose molecules can also be linked into chains to form the polysaccharides cellulose, glycogen, and starch. Chemical formula: C 6 H 12 O 6 .
