C. B. Anfinsen

C. B. Anfinsen was a scientist who discovered that the unique three-dimensional structure of a protein is determined solely by its amino acid sequence. His famous experiment showed that if a protein is unfolded and then allowed to refold in the right conditions, it can regain its original shape and function. This finding demonstrated that the information needed for a protein to fold correctly is contained within its sequence, revealing fundamental principles about how proteins achieve their functional forms in living organisms.
