What is unusual about the peptide bond compared to the other covalent bonds that form the polypeptide backbone?.
kobusy [5.1K]

When it comes to stability and the absence of atom movement surrounding the bond, <u>peptide bonds</u> behave like double bonds (peptide bonds are unusually stable compared to other types of <u>macromolecules</u>).

Peptide Bond- The -nitrogen atom of one amino acid and the carbonyl carbon of another create a peptide link, also known as an amide bond. As opposed to -amine or -carbonyl, so-called iso-peptide bonds are amide bonds between sidechain amines or carbonyl carbons.

Macromolecules- An extremely big molecule made up of hundreds or thousands of atoms, such as a protein, colloidal particle, or particularly a polymer. For instance Macromolecules include proteins, DNA, RNA, carbohydrates, and lipids.
