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.

Additional information:
There is another classification of saccharides on the basis of reducible character of the saccharide. If the anomeric -OH group is free in the structure of the saccharide it is called reducible saccharide and if it is not then it is called non- reducible saccharide .
The example of reducible saccharide are, glucose, fructose, sucrose etc. the example of non-reducible saccharide is cellulose, starch etc.

Sucrose is dextrorotatory in nature i.e it rotates the plane polarised light towards right.But on hydrolysis it yields glucose and fructose, fructose show higher degree of laevorotation than glucose dextrorotation.So on hydrolysis sucrose is laevorotatory in nature.
