WebThe term secondary structure refers to the interaction of the hydrogen bond donor and acceptor residues of the repeating peptide unit. The two most important secondary structures of proteins, the alpha helix and the beta sheet, were predicted by the American chemist Linus Pauling in the early 1950s. WebA tertiary hydrogen (as in 2-methylpropane, HOMO = − 10.4 eV) 71 is selectively removed by a bromine radical (SOMO = − 11.8 eV, ΔE = 1.4 eV), but removal of this hydrogen by a chlorine radical (SOMO = − 13.0 eV, ΔE = 3.4 eV) is less selective than with secondary and primary hydrogen atoms. In other words, the difference in energy for ...
