Circular dichroism (CD) spectroscopy measures differences in the absorption of left-handed polarized light versus right-handed polarized light that arise due to structural asymmetry. The absence of regular structure results in zero CD intensity, while an ordered structure results in a spectrum which can contain both positive and negative signals. It is an effective analytical instrument for studying the asymmetry of molecular structure.
Applications
Determination if a protein is folded
Characterization of secondary structure (α-helix,β-sheet)
Detection of changes in structure upon mutagenesis
Studying conformational stability of proteins: pH stability, denaturant stability (urea, guadinium hydrochloride), temperature, buffers, addition of stabilizers
Detection of Changes in the conformation of a protein upon protein: protein interaction
