Information on which of the following features of a protein can be obtained by means of optical rotary dispersion?
A) helical content
B) subunit content
C) disulfide interactions
D) ligand binding specificity
E) isoionic point

Question

Quizplus · Accepted Answer

Optical rotary dispersion measures the rotation of plane-polarized light as it passes through a solution of a macromolecule. This rotation is dependent on the secondary structure of the protein, specifically the helical content. Therefore, optical rotary dispersion can be used to determine the helical content of a protein, but not the subunit content, disulfide interactions, ligand binding specificity, or isoionic point.
