Which is the correct representation of peptide bond?

Options

A. `H-overset(O)overset(||)underset(|)(C)-underset(|)(N)-`
B. `-overset(O)overset(||)(C)-underset(H)underset(|)(N)-`
C. `H-overset(OH)overset(|)underset(|)(C)-underset(|)(N)-`
D. none of these

Answer

B

Explanation

Peptides are compound formed by the condensation of two or more same or different `alpha`-amino acid. The condensation occurs between amino acids with the elimination of water. In this case, the carboxyl group of one amino acid and amino group of another amino acid gets condensed with the elimination of water molecule. The resulting `-overset(O)overset(||)(C)-underset(H)underset(|)(N)-` linkage is called peptide linkage or peptide bond
