Glucose vs. Sucrose: Know the Difference
By Shumaila Saeed || Published on January 13, 2024
Glucose is a simple sugar and a primary source of energy for cells, while sucrose, table sugar, is a disaccharide composed of glucose and fructose.
Key Differences
Glucose is a monosaccharide, the simplest form of carbohydrate. Sucrose is a disaccharide, composed of one glucose and one fructose molecule.

Sucrose
A common variety of sugar found in the juices of many plants, as the sugar cane, sorghum, sugar maple, beet root, etc. It is extracted as a sweet, white crystalline substance which is valuable as a food product, and, being antiputrescent, is largely used in the preservation of fruit. Called also saccharose, cane sugar, etc. At one time the term was used by extension, for any one of the class of isomeric substances (as lactose, maltose, etc.) of which sucrose proper is the type; however this usage is now archaic.

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.
