Illustrate a glycosidic, peptide and a phospho-diester bond. | NCERT solution | Class 11 Biology | Unit-9 Biomolecules



Q.2:- Illustrate a glycosidic, peptide and a phospho-diester bond.

 

Answer

(a) Glycosidic bond is formed normally between carbon atoms, 1 and 4, of neighbouring monosaccharide units.

 

(b) Peptide bond is a covalent bond that joins the two amino acids by – NH – CO linkage.



(c) Phosphodiester bond is a strong covalent bond between phosphate and two sugar groups. Such bonds form the sugar phosphate backbone of nucleic acids.
