Question

Answer

All sacchrides /carbohydrates form glycosidic bond by eliminating water molecule

Answer

In chemistry, a glycosidic bond or glycosidic linkage is a type of covalent bond that joins a carbohydrate molecule to another group, which may or may not be another carbohydrate.

Answer

Glycosidic linkage

Glycosidic linkage is the correct answer because it refers to the specific type of linkage that occurs between two monosaccharides when a water molecule is lost. This linkage is formed through the oxygen atom, which is shared between the two monosaccharides.

Explanation:

- Monosaccharides are simple sugars, such as glucose, fructose, and galactose, which are the building blocks of carbohydrates.
- When two monosaccharides combine to form a larger carbohydrate molecule, they undergo a condensation reaction, also known as a dehydration synthesis reaction.
- In this reaction, a water molecule is lost as a byproduct, and the monosaccharides are joined together through an oxygen atom.
- The oxygen atom forms a covalent bond between the two monosaccharides, creating the glycosidic linkage.
- The glycosidic linkage is a type of ether linkage, as it involves the attachment of one monosaccharide to another through an oxygen atom.
- This linkage is responsible for the formation of disaccharides, such as sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).
- Additionally, polysaccharides, such as starch, cellulose, and glycogen, are formed by the repeated glycosidic linkages between monosaccharide units.
- The specific type of glycosidic linkage can vary depending on the monosaccharides involved and the position of the oxygen atom within the monosaccharide structure.
- For example, alpha-1,4-glycosidic linkage is formed between glucose units in starch, while beta-1,4-glycosidic linkage is formed between glucose units in cellulose.

In conclusion, the oxide linkage formed by the loss of a water molecule when two monosaccharides are joined together through an oxygen atom is called a glycosidic linkage. This linkage is essential for the formation of disaccharides and polysaccharides, which are important carbohydrates in biological systems.
