Explanation / Answer
The peptide bond is uncharged.
The plane of the peptide bond contains the following atoms: the alpha-carbon atom and CO groups of the first amino acid, the NH group and alpha-carbon of the second amino acid.
Peptide bond Polar because there is an atom of nitrogen and oxygen involved. There is a partial positive charge on the amide nitrogen, and a partial negative charge on the carbonyl oxygen. The partial double bond character makes a peptide bond rigid. The -C=O and -NH groups of the peptide bond are uncharged. The peptide bond is essentially Planar. For a pair of amino acids linked by a peptide bond, six atoms lie in the same plane: the -carbon atom and CO group from the first amino acid and the NH group and -carbon atom from the second amino acid
