Optical Rotatory Dispersion of Hemoglobin and Polypeptides

Circular dichroism and optical rotatory dispersion of proteins and polypeptides.

Quantum optical rotatory dispersion

The phenomenon of molecular optical activity manifests itself as the rotation of the plane of linear polarization when light passes through chiral media. Measurements of optical activity and its wavelength dependence, that is, optical rotatory dispersion, can reveal information about intricate properties of molecules, such as the three-dimensional arrangement of atoms comprising a molecule. Giv...

Optical Rotatory Dispersion of Catalase.

It is well recognized that the measurements of optical rotatory dispersion of proteins with strong absorption bands are extremely difficult because of the diminishing intensity of the emergent light. Until very recently, these studies were made possible only by improving the light source and also frequently by a wide opening of the slit width on the monochromator at the expense of spectral puri...

Optical Rotatory Dispersion and Circular Dichroism of

Studies of optical rotatory dispersion (ORD) and circular dichroism (CD) are reported on pepsinogen, carbamyl-, and succinylpepsinogen. From the ORD measurements in the wave length range of 600 to 300 rnp as functions of urea, temperature, and pH, it was shown that the macromolecular conformation of the three proteins differs markedly. On replacing the e-NH2 groups of the lysine residues of pep...
