Structural analysis of Hemoglobin by Circular dichroism (CD) (CAT#: STEM-MB-0633-WXH)

Introduction

Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs. Hemoglobin comprises four subunits, each having one polypeptide chain and one heme group.

Principle

Circular dichroism (CD) is a spectroscopy technique that measures the absorption difference between left and right circularly polarized light. By symmetry, this asymmetric absorption can only occur for asymmetric molecules, meaning chiral molecules.

Applications

Circular dichroism (CD) spectroscopy is a powerful technique that is sensitive to the chirality (handedness) of molecules. It can be used to study absolute stereochemistry, enantiomeric composition, racemization, enantiomeric differentiation, and molecular interactions and conformation.

Procedure

1. Sample preparation
2. Measurement by CD instrument
3. Data analysis
