Is fructose same as sucrose?

Solution

Sucrose is a disaccharide carbohydrate. It is formed when fructose and glucose molecules connect together. Vegetables and fruits contain sugar and it is abundantly found in sugar cane and sugar beets. The food industry separates this sugar from these plants to produce processed sugar like the table sugar (sucrose) and other kinds of sweeteners.
Fructose is known to many as fruit sugar. It is one of the three dietary monosaccharides (the other two are glucose and galactose). It can exist as a monosaccharide but it can also be a component of sucrose. It is the most water-soluble kind of sugar and it is directly absorbed into the during digestion.

Hence, there is a difference between Fructose and Sucrose.
