Which molecule (s) contain peptide bond (-CONH - A - Glycogen B - Lipid C - Protein D - None of the above selection are correct

C - Protein

Explanation:

Peptide bond -

The bond between the carbonyl group and the the amine group, is referred to as peptide bond.

Peptide bond is written as -

--CONH - -

From the molecules given in the question, protein molecule has peptide bond.

Since,

protein molecules are composed of amino acid chains via some force of interactions,

And, since, amino acid have a peptide bond.
