The peptide backbone is the repeating sequence of atoms in a polypeptide chain that provides structural stability and determines the overall shape of proteins. It consists of a repeating sequence of nitrogen, carbon, and oxygen atoms, linked by peptide bonds, which are crucial for the formation of secondary structures like alpha helices and beta sheets.

A polypeptide chain is a single, linear sequence of amino acids linked by peptide bonds, forming the primary structure of proteins. It folds into specific three-dimensional shapes, determining the protein's function and interactions within biological systems.

Structural stability refers to the property of a dynamical system where its qualitative behavior remains unchanged under small perturbations. It ensures that the system's critical features, such as equilibrium points and periodic orbits, are preserved, making it a fundamental concept in understanding the robustness of models in mathematics and physics.

Peptide bonds are covalent chemical bonds that link amino acids together in a polypeptide chain, forming the primary structure of proteins. They are formed through a dehydration synthesis reaction between the carboxyl group of one amino acid and the amino group of another, resulting in the release of a water molecule.
