WebMay 31, 1990 · The changes of the activity and conformation of Aspergillus niger phytase in urea were detected by far-ultraviolet circular dichroism (CD) spectra, fluorescence spectra, and enzyme activity assays. The results show that no enzyme activity can be detected after phytase is incubated for 10 h in 3.0 mol/L urea, even though at this urea concentration, … Circular dichroism is the difference . [5] The electric field of a light beam causes a linear displacement of charge when interacting with a molecule ( electric dipole ), whereas its magnetic field causes a circulation of charge ( magnetic dipole ). These two motions combined cause an excitation of an electron … See more Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light. Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible See more In general, this phenomenon will be exhibited in absorption bands of any optically active molecule. As a consequence, circular dichroism is exhibited by biological molecules, because of their dextrorotary and levorotary components.
