Over the last few years there has been an increasing interest in studying biomolecules. The function of a particular biomolecule depends on many things. How it actually works, depends critically on the spatial arrangement of the atoms from which the macromolecule is built - a conformation or 3D structure. It has been a deep-rooted belief among biologists that structure dictates function and, therefore, these studies are often involved in the elucidation of structural aspects of these molecules.
Such understanding is critical for the development of biotechnology, for both exploitation and design of natural processes and products.
There are many approaches and spectroscopic techniques used to determine the structure-function relationship of biomolecules. These include X-ray crystallography and Nuclear Magnetic Resonance (NMR) (the major techniques), chromatography, electrophoresis, mass spectrometry, fluorescence transfer, neutron difraction, electron paramagnetic resonance (EPR), vibrational and Raman spectroscopy, neutron and light scattering and circular dichroism (CD). These methods are often interconnected and, therefore providing a complementary information about the studied biomolecular structure.
