Name the sugar present in milk. How many monosaccharide units are present in it? What are such oligosaccharides called?

Name the linkage connecting monosaccharide units in polysaccharides.

Monosaccharides contain carbonyl group hence are classified, as aldose or ketose. The number of carbon atoms present in the monosaccharide molecule are also considered for classification. In which class of monosaccharide will you place fructose?

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

Which monosaccharide units are present in starch, cellulose and glucose and which linkages link these units?

Assertion: Deoxyribose, \[\ce{C5H10O4}\] is not a carbohydrate.

Reason: Carbohydrates are hydrates of carbon so compounds which follow \[\ce{C_x(H2O)_y}\] formula are carbohydrates.

Assertion: Rayon is a semi-synthetic polymer and is taken as a better choice than cotton fabric.

Reason: Mechanical and aesthetic properties of cellulose can be improved by acetylation.

Assertion: Most of the Synthetic polymers are not biodegradable.

Reason: Polymerisation process induces toxic character in organic molecules.

Synthetic polymers do not degrade in the environment for a long time. How can biodegradable synthetic polymers be made. Differentiate between biopolymers and biodegradable polymers and give examples of each type.
