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.

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.

A carboxyl group is a functional group characterized by a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group, represented as -COOH. It is a defining feature of carboxylic acids and plays a crucial role in the acidity and reactivity of organic compounds, influencing their solubility and ability to form hydrogen bonds.

An amino group consists of a nitrogen atom bonded to two hydrogen atoms and is a fundamental functional group in organic chemistry, playing a crucial role in the structure and function of amino acids and proteins. It exhibits basic properties, allowing it to participate in a wide range of chemical reactions, including forming hydrogen bonds and acting as a nucleophile in substitution reactions.

A water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom, forming a bent molecular geometry due to the lone pairs on the oxygen. This unique structure results in hydrogen bonding, making water a universal solvent with high surface tension and specific heat capacity.
