Did you know?
WebCircular dichroism (CD) measures the difference in the absorbance of left versus right circularly polarized light and is therefore sensitive to the chirality of both the molecule and the environment.343 There are two types of optically active chromophores in proteins: side groups of aromatic amino acid residues and peptide bonds. 339,343 CD … WebCircular dichroism (CD) is a powerful spectroscopic technique used to study the changes in the structure and conformation of a protein. The wavelength ranges used for the structural assessment of protein are broadly classified into three regions.

Web4.1.2.1 Electronic circular dichroism [1,3] ECD is measured using commercial ECD spectrometers operating in the UV–Visible spectral region (∼190–600 nm). ECD spectra are normally presented as differential molar extinction, Δ ɛ, in units of M −1 cm −1, where M is molarity (mol L −1) as a function of wavelength. WebThe transmitted light is then elliptically polarized, and this phenomenon is called circular dichroism (CD) and is expressed by the ellipticity θ (Fig. 4). A plot of the wavelength dependence of this ellipticity is called a circular dichroism spectrum (CD spectrum). Fig. 4-1 Principles of CD：unequal absorption of circularly polarized light
