The simulation of bovine serum albumin vibration spectrum in THz domain
JOURNAL OF OPTOELECTRONICS AND ADVANCED MATERIALS, 12:135-140, JAN 2010

Biomolecules have distinct signatures in THz spectral region. Here we reconstructed the THz theoretical spectrum of hydrated bovine serum albumin (BSA), a protein with unknown 3D structure. The THz spectrum of dry BSA was simulated using a 3D model of the protein. THz theoretical spectra of water were calculated using four water models. By adding the dry BSA and water theoretical spectra we obtained a good correlation with the experimental data that were recorded on a 10% w/w BSA solution.
