Answer:
Through glycosidic bond.
Explanation:
Disaccharide:
Disaccharide is simple polysaccharide. It is formed when two monosaccharides combine together. The monosaccharides are combine through dehydration reaction as a result glycosidic bond is formed between two monosccharides with removal of water molecule.
The reaction is also called condensation reaction.
There are two types of disaccharides:
Reducing disaccharides
These are hemiacetal and have reactive carbonyl group. They can be oxidized to other products.
Non - reducing disaccharides
These are acetals and can not be easily oxidized like reducing disaccharides.
Glycosidic bond:
It is covalent bond formed between the carbohydrate and another molecule such as monosaccharide.
This bond can be alpha or beta glycosidic bond.
