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 ...

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 ...
