Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...

We used interferon α-2b (IFN) because it is representative of four-helical-bundle proteins with accessible disulfide bonds ... indicating that IFN's tertiary structure is preserved 7 ...

like proteins it requires to undergo changes to form a specific tertiary structure. The scaffold for this structure is provided by secondary structural elements which are hydrogen bonds within the ...

Two sets of 1D 1 H-NMR experiments, using 700 MHz and 600 MHz instruments at 298 K were carried out to determine the presence and the extent of tertiary structure. Structural similarity among members ...

Researchers at Ruhr University Bochum, Germany, have shed light on the structure of supercritical ... within which they are then connected by hydrogen bonds. The Bochum-based team has now ...

It has a giant lattice structure with strong electrostatic forces ... substances have many atoms joined together by covalent bonds. Diamond, graphite and graphene are forms of carbon with ...
