The four atom - C(=O) NH is called peptide bond and forms a rigid planar unit because of the partial double bond character.. So the last option is correct
The peptide bond is formed between the carboxyl group of one amino acid and amino group of second. it may have polar and non polar side chains it depends on amino acid.

Which of the following is true about proteins? a. Peptides linkages are made between the side chain and the carboxyl group. b. Hydrogen bonding between the NH and CEO of the backbone results in only alpha helices! c. Electrostatic interactions between the NH and C=O of the backbone results in only beta sheets. d. Quaternary structures of proteins involve multiple peptide chains interacting together.

Review| Constants| Periodic Table Protein structure is conceptually divided into four levels, from most basic to higher order Primary structure describes the order of amino acids in the peptide chain. Secondary structure describes the basic three-dimensional structures, a-helices and B sheets. Tertiary structure describes how the secondary structures come together to form an individual globular protein. Quatemary structure results from individual proteins coming together to form multi-subunit protein complexes Part A Complete the following vocabulary exercise relating to the level...
