Name: Study of Fibrous protein by Linear dichroism (LD)
SKU: STEM-ST-0109-WXH
Rating: 5 (1 reviews)

Introduction

In molecular biology, fibrous proteins or scleroproteins are one of the three main classifications of protein structure (alongside globular and membrane proteins). Fibrous proteins are made up of elongated or fibrous polypeptide chains which form filamentous and sheet-like structures. These kind of protein can be distinguished from globular protein by its low solubility in water. Such proteins serve protective and structural roles by forming connective tissue, tendons, bone matrices, and muscle fiber.

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.
