TERAHERTZ DANCE OF AMINO ACIDS

JACS: RUB chemists explain the fingerprint of dissolved glycine in the Terahertz range - Combination of molecular-dynamics simulations and spectroscopy is key to success. The team led by Prof Dr Martina Havenith-Newen and Prof Dr Dominik Marx published their report in the “Journal of the American Chemical Society”.

Chemists at the Ruhr-Universität Bochum (RUB) have, for the first time, completely analysed the fingerprint region of the Terahertz spectrum of a biologically relevant molecule in water, in this case, an amino acid. By combining spectroscopy and molecular-dynamics simulations, they rendered the motion of the most basic amino acid, glycine, visible in an aqueous solution. Their results have disproved the long-standing theory that frequencies in the Terahertz range provide no information regarding the amino acid’s motion. The team led by Prof Dr Martina Havenith-Newen and Prof Dr Dominik Marx published their report in the “Journal of the American Chemical Society” (JACS).
