Study of Flavonoid-DNA Interaction by Linear dichroism (LD) (CAT#: STEM-ST-0130-WXH)

Introduction

Flavonoids are used by vegetables for their growth and defence against plaques. They belong to a class of low-molecular-weight phenolic compounds that are widely distributed in the plant kingdom. They constitute one of the most characteristic classes of compounds in higher plants.




Principle

Linear dichroism (LD) or diattenuation is the difference between absorption of light polarized parallel and polarized perpendicular to an orientation axis. It is the property of a material whose transmittance depends on the orientation of linearly polarized light incident upon it. LD measurements are based on the interaction between matter and light and thus are a form of electromagnetic spectroscopy.

Applications

Study the functionality and structure of molecules.

Materials
