... by atoms with similar electronegativity, which each donate a valence electron to form a shared electron-pair bond. A polypeptide chain is composed of adjacent amino acids, where the α-carboxyl group of an amino acid is linked to the α-amino group of the adjacent amino acid. This chain acts as a rigid backbone, as the peptide bonds are planar, although side-chains can move more freely. As a peptide ... structure of the polypeptide chain and can be the final structure for some proteins. The hydrophobic effect is series of interactions, which hold significant importance in stabilising te...
