What is the process of changing the 3 dimensional structure of protein called?

The process of changing the three-dimensional structure of a protein is called protein folding. This involves the protein adopting its functional conformation, driven by interactions among its amino acids and environmental factors. Misfolding can lead to loss of function or diseases, such as Alzheimer's, indicating the importance of proper folding. Additionally, proteins can undergo conformational changes in response to factors like binding to ligands or changes in the cellular environment.
