Sucralose

Glucose and fructose are monosaccharide sugars. A monosaccharide is the smallest unit of sugar, mono meaning 1.
Sucrose is commonly called table sugar and is a disaccharide. A disaccharide is a sugar that is made up of two sugar units, di meaning 2.
Sucrose is produced as glucose and fructose are joined together by a condensation reaction. In the process a water molecule is eliminated. See the following equation.
C6H12O6 + C6H12O6 => C12H22O11 + H2O
glucose   + fructose => sucrose + water
Hint: This is an easy way to remember the chemical formula for sucrose. 2 x C6H12O6 - H2O = C12H22O11
The molecular formula for sucrose is C12H22O11

Sugars are a white crystalline group of soluble carbohydrates that are sweet tasting in nature. These sugar molecules include glucose, sucrose, lactose, fructose, maltose, lactose and galactose. Sugar molecules are classified asmonosaccharides or disaccharides. The following table lists the common sugar molecules are their chemical formula.

The monosaccharides glucose, galactose and fructose all have the same molecular formula but they vary in their molecular structure.
