Question

# Name two monosaccharide present in sucrose.

Hint: Saccharides are basically a group of organic compounds. The general formula of saccharide is ${C_n}{H_{2n}}{O_n}$. The ratio of hydrogen and oxygen is always $2:1$. Saccharides are also called carbohydrates. These are biomolecules.

On the basis of number of saccharide molecules attached with each other saccharides are classified into four different types These are,
Mono saccharides, disaccharides, trisaccharide, and polysaccharide etc.
The common example of disaccharide is sucrose. Sucrose contains glucose and fructose in one molecule . The structure of sucrose is shown below.

In this structure the bonding between glucose and fructose is called glycosidic linkage. And this glycosidic linkage is at ${C_1}$ carbon of glucose and ${C_5}$ carbon of fructose.
