A polymer of amino acids, known as a polypeptide, is a chain formed through the covalent bonding of numerous amino acids. The sequence of amino acids in a polypeptide determines its unique structure and function. Polypeptides can range from simple chains to complex, folded structures that make up the vast majority of proteins found in living organisms. These proteins play a crucial role in various biological processes, including structural support, enzymatic catalysis, transport, signalling, and energy storage.
