D-glucose, also known as dextrose, is a natural monosaccharide and carbohydrate that plays a crucial role in metabolism, with the human body requiring a continuous and stable supply. This simple sugar is the body's primary source of energy, and its use offers significant benefits for athletes, individuals with hypoglycemia, and those needing quick revitalization.

In humans, approximately 180–220 grams of glucose are produced by the liver over 24 hours to ensure a stable supply for the body's energy needs. D-glucose, the most abundant monosaccharide, is crucial for both energy production and the creation of complex biomolecules in nearly all living organisms.

Dextrose and glucose are terms often used interchangeably, but a key chemical difference exists. Specifically, dextrose monohydrate is the hydrated form of D-glucose, meaning it is a D-glucose molecule that has one molecule of water attached.

According to scientific consensus, dextrose is also known as glucose, the body's most fundamental energy source. Both terms are used interchangeably to refer to this monosaccharide, which can be found in a variety of foods and is vital for cellular function.

From a scientific perspective, glucose and dextrose are fundamentally the same simple sugar molecule, D-glucose. However, the terms are often used differently, with one describing the sugar in a biological context and the other referencing its commercially derived form in food products.

As constitutional isomers, D-glucose and D-fructose share the same chemical formula ($C_6H_{12}O_6$), but are differentiated by their functional groups. This structural distinction is the basis of their unique biochemical roles, affecting everything from how the body metabolizes them to their characteristic sweetness and ring structures.

D-glucose, also known as dextrose, is the most abundant monosaccharide on Earth and the primary energy source for most living organisms. However, its non-superimposable mirror image, L-glucose, is a rare synthetic compound with profoundly different biological effects. So, what is the difference between D-glucose and L-glucose?

D-glucose is the most abundant monosaccharide in nature, yet its close relatives, D-galactose and D-mannose, play equally critical but distinct roles in biology. These three hexoses share the same chemical formula, C6H12O6, but are differentiated by the specific arrangement of hydroxyl (-OH) groups around their carbon atoms, which profoundly impacts their function.

Despite sharing the same chemical formula, $C_6H_{12}O_6$, D-glucose and D-galactose are epimers, a specific type of stereoisomer that varies only at one chiral center. This critical difference in their molecular structure at the fourth carbon atom fundamentally distinguishes them in biochemical pathways.

Despite being a fundamental building block for complex carbohydrates, D-glucose is not a polysaccharide. It is correctly classified as a simple sugar, also known as a monosaccharide, which serves as the repeating unit for much larger molecules such as starch and cellulose.
