Identify the substances having glycosidic bond and peptide bond, respectively in their structure.
Identify the substances having glycosidic bond and peptide bond, respectively in their structure.
The correct option is B Inulin, Insulin
The correct option is B:
Explanation of the correct option:
- Inulin is a polysaccharide with a β(2→1)glycosidic bond. Insulin is a peptide-bonded protein molecule.
Explanation of the incorrect option:
Option A:
Cellulose is a linear polymer made up of β-1,4-glycosidic linkages that connect d-glucopyranose units. The ammonium salt of choline is linked to the phosphate by an ester bond in lecithin.
Option C:
Chitin is a N-acetyl-d-glucosamine linear polymer linked by a β-(1,4)-glycosidic bond. Cholesterol is a cholestanoid made composed of cholestane with a 5,6-position double bond and a 3-β-hydroxy group.
Option D:
Glycerol crystals are entirely hydrogen bound, with each molecule acting as a donor in three hydrogen bonds. Trypsin is an enzyme that breaks down proteins into smaller peptides by catalysing the hydrolysis of peptide bonds.
Final answer: Cellulose and lecithin have glycosidic bond and peptide bond, respectively in their structure.
