Question

Select the option that correctly identifies the chemical bonds present in the given biomolecules.

Polysaccharides - A, Proteins - B, Fats - C, Water - D

• A. A - Ester,B - Peptide, C - Glycosidic, D - Hydrogen
• B. A - Glycosidic, B - Peptide, C - Ester, D - Hydrogen
• C. A - Glycosidic, B - Peptide, C - Hydrogen, D - Ester
• D. A - Hydrogen, B - Ester, C - Peptide, D - Glycosidic

Answer 1

The correct option is B A - Glycosidic, B - Peptide, C - Ester, D - Hydrogen

• In polysaccharides, monosaccharides are linked together by glycosidic bond $(C-O-C)$. It is formed by dehydration between two carbon atoms of two adjacent monosaccharides.
• Water has hydrogen bonding as the hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule.
• Amino acids in a protein are linked through peptide bonds whereas ester bond is present in fats .

So, the correct answer is 'A - Glycosidic, B - Peptide, C - Ester, D - Hydrogen'.
