What are glycosidic linkages? In which type of biomolecules are they present?

Carbohydrates are essential for life in both plants and animals. Name the carbohydrates that are used as storage molecules in plants and animals, also name the carbohydrate which is present in wood or in the fibre of cotton cloth.

On the basis of which evidences D-glucose was assigned the following structure?

Label the glucose and fructose units in the following disaccharide and identify anomeric carbon atoms in these units. Is the sugar reducing in nature? Explain.

Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : β-glycosidic linkage is present in maltose,

Reason : Maltose is composed of two glucose units in which C–1 of one glucose unit is linked to C–4 of another glucose unit.

Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : Deoxyribose, C₅H₁₀O₄ is not a carbohydrate.

Reason : Carbohydrates are hydrates of carbon so compounds which follow Cx(H₂O)y formula are carbohydrates.

Write the reactions of D-glucose which can’t be explained by its open-chain structure. How can cyclic structure of glucose explain these reactions?

Three structures are given below in which two glucose units are linked. Which of these linkages between glucose units are between C1 and C4 and which linkages are between C1 and C6.Is the compound (I) reducing in nature? Explain.
