WebAnd the term "conformation" just refers to a protein's folded 3D structure, or, in other words, the active form of a protein. And next, we can review what the term "denatured" means … WebDec 5, 2024 · Protein folding is the process by which a protein takes its shape from a string of building blocks to its final three-dimensional structure, which determines its function. By better predicting how proteins take their structure, or "fold," scientists can more quickly develop drugs that, for example, block the action of crucial viral proteins.
