Product Description
D(+)-Glucose is a six-carbon sugar containing an aldehyde group, with the molecular formula C6H12O6. As the most vital monosaccharide in living organisms, it functions chiefly as an energy source to support physiological activities. The complete oxidation of 1 mole of glucose releases 2,870 kJ (686 kcal) of energy, satisfying 70%-80% of the body’s total energy demands. Apart from energy supply, glucose provides carbon skeletons for biosynthetic pathways, acts as a critical precursor for lipid synthesis, and serves as the structural framework for synthesizing essential amino acids.

Product Application
D-Glucose plays an essential role in diverse metabolic processes, including the enzymatic synthesis of cyclohexyl-α- and β-D-glucosides. It is widely applied in type 2 diabetes research and represents the predominant aldohexose detected in living organisms. As the primary energy source for the brain, its bioavailability directly modulates cognitive performance and mental functions.
