Identify the substances having glycosidic bond and peptide bond, respectively in their structure

  1. Glycerol, trypsin
  2. Cellulose, lecithin
  3. Inulin, insulin
  4. Chitin, cholesterol

Answer

(3) Inulin, insulin

Solution

As per NCERT, in a polysaccharide the individual monosaccharides are linked by a glycosidic bond, and in a protein the amino acids are linked by a peptide bond.

Inulin is a polymer of fructose (glycosidic bonds); insulin is a protein (peptide bonds).

Glycerol is a trihydroxy alcohol (no glycosidic bond); lecithin is a phospholipid and cholesterol is a steroid (no peptide bond).

The correct pair is inulin, insulin.
