Question
Illustrate a glycosidic, peptide and a phospho-diester bond.
✓
Answer
Glycosidic bond is formed normally between carbon atoms, 1 and 4, of neighbouring monosaccharide units.
Peptide bond is a covalent bond that joins the two amino acids by – NH – CO linkage.
Phosphodiester bond is a strong covalent bond between phosphate and two sugar groups. Such bonds form the sugar phosphate backbone of nucleic acids.
