Glucose is a six-carbon sugar containing an aldehyde group, with the molecular formula C6H12O6. It is the most essential monosaccharide in living organisms and serves primarily to supply the energy necessary for the body’s physiological functions. The complete oxidation of one mole of glucose releases 2870 kJ (686 kcal) of energy, which accounts for about 70%–80% of the body’s total energy needs. Besides being an energy source, glucose also provides the carbon framework required for biosynthesis and acts as a key precursor in the formation of lipids. Additionally, it contributes the structural backbone for synthesizing essential amino acids in the human body.

Product Application of D(+)-Glucose CAS#50-99-7
D-Anhydrous glucose participates in a variety of metabolic pathways, including the enzymatic synthesis of cyclohexyl-α and β-D-glucosides. It plays an important role in type 2 diabetes research and in detecting the most common aldohexose found in living organisms. Since it serves as the brain’s primary energy source, its availability has a significant impact on cognitive and mental functions.
