Conformational analysis of glucagon solutions by Circular dichroism (CD) (CAT#: STEM-MB-0643-WXH)

Introduction

Glucagon is a hormone that your pancreas makes to help regulate your blood glucose (sugar) levels. Glucagon increases your blood sugar level and prevents it from dropping too low, whereas insulin, another hormone, decreases blood sugar levels.

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
