Explanation – Protein folding refers to the process in which a polypeptide chain (a linear chain of amino acids) transforms into a functional three-dimensional structure, which is essential for its biological activity. This three-dimensional structure is determined by the specific sequence of amino acids in the protein and the interactions between them, as well as interactions with the surrounding environment. Protein folding plays a crucial role in protein function, as it allows the protein to adopt a specific conformation that enables it to perform its designated tasks within cells.
