The determination of the secondary and tertiary structure of biomolecules, especially proteins and nucleic acids, is essential for the investigation of biomolecules' functions in their native, biologically active conformation. Circular dichroism (CD) is a powerful tool for understanding the secondary and tertiary structure of proteins, nucleic acids, as well as protein-ligand complexes. It can also characterize the binding interactions of non-immobilized molecules in the solution. Circular Dichroism Spectroscopy https://www.creative-biostruct....ure.com/circular-dic
