The molecular formula of the compound in the image is
which is the molecular formula of glucose.
Glucose is a simple sugar that is the primary source of energy for cells which is a six-carbon monosaccharide, meaning that it has six carbon atoms and one aldehyde functional group.
Glucose is a chiral molecule having two non-superimposable mirror images. As we can see form the image the D-isomer of glucose, which is the most common form of glucose found in nature. Glucose is an essential nutrient for all living organisms and can be used to produce energy for cells, and it is also a building block of other important molecules, such as starch and glycogen.
