A new ligand extends the half-life of peptide drugs from minutes to days

18-Jul-2017

Peptides are biological molecules, made up of short sequences of amino acids. Because they are easy to synthesize, show low toxicity and high efficiency, peptides such as insulin and other hormones can be used as drugs. But peptides are quickly cleared by the kidneys, which means that we can only ...

Terahertz dance of amino acids

RUB chemists explain the fingerprint of dissolved glycine in the Terahertz range

01-Apr-2014

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 ...
