The folding of protein chains refers to the process by which a linear sequence of amino acids in a polypeptide chain folds into a specific three-dimensional shape. This shape is critical for the protein's functionality, as it determines how the protein interacts with other molecules and performs its biological roles. Understanding this folding process has implications in various fields, including biology, chemistry, and knot theory, as it can be modeled using mathematical concepts related to knots.
