Glucose vs. Dextrose: Know the Difference
By Shumaila Saeed || Published on January 14, 2024
Glucose is a simple sugar and key energy source for cells, while dextrose, chemically identical to glucose, specifically refers to glucose found in the D-form.
Key Differences
Glucose is a simple sugar, a monosaccharide, and a primary energy source for living organisms. Dextrose, essentially glucose, refers specifically to the D-form of glucose, a natural form found in living organisms.

Glucose is essential for cellular metabolism and is found in the blood of animals as blood sugar. Dextrose, often used in medical contexts, is the same glucose molecule but highlights its dextrorotatory properties, meaning it rotates plane-polarized light to the right.

Glucose
A variety of sugar occurring in nature very abundantly, as in ripe grapes, and in honey, and produced in great quantities from starch, etc., by the action of heat and acids. It is only about half as sweet as cane sugar. Called also dextrose, grape sugar, diabetic sugar, and starch sugar. See Dextrose.

Dextrose
A sirupy, or white crystalline, variety of sugar, C6H12O6 (so called from turning the plane of polarization to the right), occurring in many ripe fruits, and also called glucose. Dextrose and levulose are obtained by the inversion of cane sugar or sucrose, and hence the mixture is called called invert sugar. Dextrose is chiefly obtained by the action of heat and acids on starch, and hence called also starch sugar. It is also formed from starchy food by the action of the amylolytic ferments of saliva and pancreatic juice.
