Multiple choice

Match the column - I (polysaccharides) with column – II (their linkages).

 
Column – I Column – II
A. Chitosan 1. Linear polymer of β(1 → 3) and β(1 → 6) linked glucose units in the ratio 11 : 1
B. Curdlan 2. Consists of β-(1, 3)-linked glucose residues
C. Chrysolaminarin 3. Composed of randomly distributed β-(1 - 4)-linked D-glucosamine and N-acetyl-D-glucosamine

  1. A - 1, B - 2, C - 3

  2. A - 1, B - 3, C - 2

  3. A - 2, B - 1, C - 3

  4. A - 2, B - 3, C - 1

  5. A - 3, B - 2, C - 1

E Correct answer
Explanation

This option is correct because all polysaccharides are correctly matched with their linkages. Chitosan is composed of randomly distributed β-(1 - 4)-linked D-glucosamine and N-acetyl-D-glucosamine. Curdlan consists of β-(1, 3)-linked glucose residues. Chrysolaminarin is a linear polymer of β(1 → 3) and β(1 → 6) linked glucose units in the ratio 11 : 1.
